There are several ways to aerate your fish tank, and these methods will be discussed in this article. Before discussing specific methods, it is important to address the surface area of ​​water in the fish tank. The larger this surface area, the more water is in contact with the air. This results in greater absorption of oxygen by water. Therefore, you should try to maximize the surface area of your fish tank.

Basic Oxygen and Carbon Dioxide Exchange Introduction

When your fish breathe, they absorb oxygen from the tank, and their body converts the oxygen to carbon dioxide and then exhales. Oxygen and carbon dioxide are also exchanged on the surface of the water. Carbon dioxide is released from the water into the air. This is important because if you don't let carbon dioxide escape into the atmosphere, your fish will die - it will only accumulate in the tank, causing your fish to slowly suffocate to death. You may need a carbon dioxide diffuser.

When carbon dioxide is released from water into the air, oxygen is also absorbed from the air into the water. This is important because it increases the oxygen content in the aquarium water and provides the fish with the oxygen they need to breathe. For this air exchange to occur, however, the surface tension of the water must be broken - this allows the carbon dioxide molecules to be released and oxygen to be absorbed. Agitating the surface breaks this surface tension and allows proper gas exchange.

Temperature and oxygen concentration

As your tank temperature rises, the oxygen content will decrease because your tank's water evaporation rate will increase. Therefore, the higher the temperature you keep in your tank, the more you need to know if your fish is getting enough oxygen. Once your temperature exceeds 800 degrees Fahrenheit, you may need to provide some aerating equipment listed below apart from the filter in tank.

What Common Aerating Equipment Are There

Filter

For many aquariums, a simple hob (hanging on back) filter will fully aerate your tank. Many filters have an output that drips water into the surface of the tank, thus providing sufficient surface agitation. This surface disturbance increases the surface area that is in contact with the atmosphere and therefore increases the absorption of oxygen. In addition, the good filter in tank fish filter, which is important because it moves the bottom water of the fish tank (water that cannot get oxygen from the air) to the top surface, which can increase the oxygen concentration.

Pros / cons of filters

-Help increase aeration / oxygen content

-Increase the water circulation in the tank, thus the surface area

-Rotate tank water up from the bottom

-May create blind spots depending on the location of the filter

Power Head

If your filter doesn't interfere with the surface enough or provide enough circulation, you can use a powerhead as well. The powerhead siphons water out of the tank and mixes it with the exhausted air. Many powerheads also allow you to adjust the amount of air they inhale, which allows you to adjust the number of bubbles generated (see the paragraph on bubble stones below to learn how bubbles help ventilation).

The powerhead can also be used to eliminate dead spots in the water tank-areas with particularly low water circulation. A carefully placed powerhead can increase the circulation of your tank in these areas. Filters, air stones, and decorations often fail to adequately aerate large aquariums. Therefore, powerheads are often the method of choice for large tanks. However, you can easily supply too much current in a small to medium-sized aquarium with powerheads, so be sure to buy a tank rated for smaller or buy a tank with adjustable flow.

Pros and cons of a powerhead

-Become a good source of supplemental aeration

-Can help deal with blind spots in the tank

-Can increase overall aeration

Air Stone

The air stone is a porous stone that is connected to an air pump and generates air bubbles in the fish tank. Many people think these pumps are too noisy, so they choose not to use air stones. However, placing the pump on a sponge usually reduces noise significantly. Some amateurs really like the bubble wall in the fish tank, so they will use it even without further inflation. In fact, it is not the bubbles that provide oxygen to the water (this is a common misconception), but the ability of bubbles to disturb the water surface and provide more water circulation helps increase the oxygen concentration in the water tank.

Pros and cons of Air Stone

-Can be installed in almost any tank

-Adjustable flow rate, suitable for any size tank

-Helps increase surface agitation and circulation

Although many factors play a role in keeping the fish healthy, aeration is one of the most important factors. Properly aerating the tank will allow your fish to breathe normally, which is important for good health. The most commonly used aeration equipment in fish tanks are filters, powerheads and air stones, which Senzeal can provide. Use any combination you like to give your fish the oxygen they need. We have external fish tank filter for sale, welcome to buy.

Aquarium landscaping is an art. It creates a mini-world, a living ecosystem. Regardless of whether it is from moss on rocks, flowers from the shore, or algae and fish from the water, you need to consider it during the landscaping process. If you want to make a fish tank, you need to know the methods of aquarium landscaping. So what are the common methods of aquarium landscaping? Let’s take a look together.

What are the common aquarium landscaping methods

1. Ladder aquarium landscaping

This method is suitable for wall-mounted fish tanks. The basic shape is a step-by-step setting method from the background water plants to the foreground.

Critical notes: Put matching elements first, such as stone or driftwood. Pay attention to the texture of the material when placing it, and present a regular rhythm on the irregular material. The same pieces of wood and stone can produce different effects at different angles. The matching elements and water plants must be connected together without interruption to have a continuous overall sense. In the beginning, some plants with a faster growth rate can be planted in the foreground, and plants with a slower growth can be planted in the front and middle scenes. Except for the foreground grass, each kind of water weed is planted in clumps as much as possible. It is best to have only one clump of the same kind in the aquarium. The size and arrangement of each clump of plants are as irregular as possible, so as not to make the landscape too rigid. In principle, the ladder aquarium landscaping method gradually increases from the foreground to the background, but it can also be decorated with a few tall but less dense water weeds as the foreground, which can better show the three-dimensional effect of the landscape. You may need a set of tools for aquascaping.

2.Double-sided set method of aquascaping

Most of them are set techniques that can be viewed on both sides in the aquarium with compartment-style landscaping.

Critical notes: The principle of this method is the same as that of the ladder landscape method, but because both sides of the ornamental are taken into account, both sides must have beauty during landscaping. The middle line of the fish tank can be used as the location of the background grass, and the middle and foreground grass is planted on both sides, so that the layering and three-dimensional sense of the landscape can be more prominent, especially in fish tanks that are not very wide. The technique can more show the interestingness of double-sided aquarium landscaping.

3.Aquascaping with a three-dimensional fish tank

In addition to enjoying the scenery under the water, there must be scenery on the water surface.

Critical notes: Usually, an open-type fish tank is used together with a ceiling-mounted hanging lamp to better show the growth aesthetics of a three-dimensional aquatic landscape. When setting the scene, you can use more watery and floating water weeds, so that you can better enjoy the pleasure of changing the landscape in and out of the water. The three-dimensional aquatic landscaping fish tank is a more difficult landscaping method because it requires a higher level of configuration and there are more problems to consider when landscaping.

Precautions for fish tank landscaping

In the landscape design of aquatic fish tanks, sunken wood or aquarium landscape rock is often used as the accompanying scene. If there are no sunken wood or stones in the small plants, the scenery of the plants will appear stiff and rigid; with them, the scenery of the plants will become more natural and attractive. Therefore, sunken wood and stones have become indispensable companion elements to water plants.

Sunken wood and stubble in forests, mountains or swamps are slowly weathered through long-term sun exposure and wind and rain. Common sunken wood from Brazil is collected from moist or swamp areas. The surface of the material is beautiful, but the texture is relatively soft. The sunken wood made in the Philippines is very hard. Because it is heavier than water, it soon sinks to the bottom. The internal material also does not decay, which is one of the most ideal landscape materials.

The sunken wood set off the water and grass scenery. Although it has played a great role, it has its shortcomings. The reason is that when put into water, it changes the pH of the water, which is bad for the growth of water plants. Stone is also an ideal companion element. It is much more convenient to collect than sunken wood, but it also has disadvantages. It continuously releases alkaline substances into the water and changes the pH of the water. However, it is suitable to be used as companion material for banyan aquatic plants, because banyan aquatic plants are adapted to live in a limestone water environment.

There are many different aspects of ornament to consider when building an underwater scene in your aquarium. Remember, you are creating a complete world for your fish. This is a three-dimensional space where your pets can eat, breathe, sleep, hide and play.

Guide to Fish Tank Decorating

So where do you start? It is best to start from the bottom.

The first thing to decide is what to put in the bottom of the tank. There are so many substances to choose from. Grit is the most commonly used tropical tank to decorate the bottom. It is easy to clean and if you need to fix some plants, it has a little weight. Gravel comes in many different colors and textures to match your landscape with whatever you can choose. Adding larger river stones or marble can add aesthetics and increase the size of plain gravel.

Once the substrate is selected, it's time to start looking for the perfect background. Some are flat, some are placed behind the aquarium and some are three-dimensional, placed inside the glass behind the aquarium. The purpose of both is to hide the unsightly water filter hanging behind the water tank. Whether you decide to choose a filter is more a matter of preference. For your aquatic life, it is recommended that you place one. But keep in mind that landscapes hanging in the water should be added to your aquarium cleaning task list.

The next step in fish tank ornaments is the fun part, and choosing one or two dramatic ornaments will be the focus of your entire underwater scene. No matter what it looks like, fish will love it, but make sure it has enough hiding place. These aquarium ornaments can be almost anything, sunken ships, hollowed logs, caves, castles or houses, and many more. Be sure to pay close attention to the size of these trim pieces to match your fish and tank. You need to have enough space for the fish to hide underneath, as well as enough space for your pet to swim freely on it. Once you have selected a large accessory, you can continue to look for small accessories.

Auxiliary ornaments can be useful features that are added to your tank for specific uses. If you have some live fish that need more oxygen, you can look for rivers and bridges underwater or bubbling treasure chests. These ornaments often require air pumps to drive them and can replace ordinary old air stones. Some fish seem to be happy when swimming in turbulent currents, which is a great way to provide them. Another functional ornament is the diving light ornament. This type of ornament provides a soft glow in the aquarium, just as seen in aquarium hoods without strong, bright light. These glowing features usually have different colors to enhance the hue of the tank.

The final step in aquarium ornament is choosing the right plants. This is the last touch of personality and color in your aquarium. Decide if you want many plants or just some. If you plan to keep larger fish, it's best to use only a few because they will rearrange what they can move. If you are raising small fish, you may need more plants so that the tank will look fuller. Then you need to decide whether you want to use real or plastic plants. Similarly, the bigger the fish, you should choose a more durable plastic plant. If you have smaller fish, it doesn't matter which one you choose, because they won't hurt real or fake plants.

Once you have selected all the fish tank ornaments, you may need to rearrange it a few times before it is absolutely perfect. Just keep trying until you get it right and your fish will like you for it.

Choose the Perfect Fish Tank Decoration

To choose the perfect fish tank decorations, evaluate it yourself. Your fish tank decoration should help bring your imagination to life-themes and contrasts and perfect color combinations.

First determine a theme or a certain color, this is the basic step to achieve your ultimate goal and create a beautiful and fun home for your fish. When buying aquarium accessories, keep in mind the kind of fish you want. What do you think makes them feel comfortable or stressed? By studying the natural habitat of fish, you can design decorations based on their benefits to fish.

If you have a lot of bright colors in your tank, consider choosing brightly colored fish, as these colors automatically complement each other.

Be careful not to use sharp-edged decorations as they may hurt your fish. It is also wise not to use too many large fish tank decorations because your fish usually hides behind them and it is difficult to see your fish. One or two large decorations are sufficient, depending on the size of the tank. Always clean any new decorations you put in your fish tank. You can usually rinse them off with boiling water and a toothbrush.

You also don't want too many decorations in a fish tank, because it will clutter your fish tank. With the right combination of fish tank accessories, you can turn your fish tank into a classic masterpiece.

Remember, no matter which theme, color, or fish you choose, if you follow the instructions and take the advice and tricks, you will have a rather unique design created underwater to reflect on you and to your guests, and your friends, Very relaxing and living space. Aquarium decorations are very beneficial for your fish because most of your fish will want to feel safe. With the fish tank decoration, they know that there are places to hide or play, and they feel satisfied.

The core problem of underwater activity of divers is that humans cannot ingest oxygen from water, therefore, it is necessary to carry gas cylinders or to supply gas from the water surface, and the breathing problem has become one of the most complicated technologies in diving technology. But the water actually dissolves a certain amount of oxygen, fish is through the gills to absorb oxygen from the water to maintain life. In theory, if you can master the rapid uptake of oxygen from water, then humans do not need to carry gas in the underwater activities. But keeping breathing for a long time under water has always been considered unthinkable and impossible, scuba diving can only continue to be carried out underwater by carrying air or by piping. Because fish can absorb oxygen from the water by their gills, humans and mammals don't have gills, and they can't use oxygen in the water to support life.

Do you know how fish breathe underwater？

Let the human fish breathe oxygen in the water for a long time to survive in the water, it sounds like science fiction, and Danish scientists have recently been able to get oxygen permanently underwater, which is a step toward that goal. It's because of the kind of crystal material they developed, this synthetic material is named Neptune crystal AquamanCrystal. This synthetic material can continuously ingest oxygen from air and water without any other means. The oxygen absorbed by the crystal can be released as long as it is heated slightly or exposed to low oxygen pressure. At present, it is difficult to produce this kind of synthetic crystal material in large quantities.

The implications of this finding are profound, says Christina Mackenzie, a professor at the university of Denmark, who led the research. She told the science daily: "this material can absorb oxygen from the air. Patients with respiratory dysfunction need daily oxygen, the technology will allow patients to get rid of heavy oxygen tanks. Divers may also use the technology in the future to carry a small amount of this crystal grain. The diver breathes the material into the water to absorb oxygen that is dissolved in water, so there is no need to carry gas cylinders or supply the gas from the water. So they named the crystal AquamanCrystal.

Neptune crystals have a spongy composition that absorbs oxygen.

Neptune crystals absorb oxygen and rely on cobalt ions. This is very similar to the ability of hemoglobin to absorb oxygen. Because oxygen is difficult to dissolve in water and blood, all living things on earth use metal ions to combine and transport oxygen. The hemoglobin in the blood of people and many animals depends on the combination of iron and oxygen. Myoglobin, the myoglobin in muscle cells, is also a similar molecule. Animals such as crabs and spiders rely on copper ions to combine and transport oxygen. The ability of metal ions to absorb oxygen is huge. So it's not surprising that this crystal glass has a powerful ability to absorb oxygen.

More and more people like to make an aquarium landscape, but they do not know the specific steps, have been afraid to try this! Today, we will tell you a brief introduction about the process of novice landscape.

First of all, prepare a 60*45*45 fish tank. It is best to use   fish tank filter box, which flow is up to 600L per hour, set up LED water grass fish tank light is the best. If you want to plant red grass, the kind of water grass lamp with red light beads will be better.

What kind of fish tank materials will be used? Rhododendron Root, substrate, blue dragon stone, volcanic stone (debris). In order to better activate the bottom of the aquarium, we also prepare bacterium powder. Water plants will be planted Java Fern, Anubias Nana and Little Triangle Moss.

This fish tank landscape belongs to the convex structure. Firstly, laying the bacterium powder in the middle of the fish tank, then covered with volcanic rock particles, and finally surrounded with blue dragon stone! The function of the blue dragon stone is mainly to isolate the external substrate.

Fill in the space of substrate, then tidy up, preferably with an aquarium brush, it's easier to clean.

In the middle of the tank, the position of laid blue dragon stone, filled with a right amount of water grass mud which can provide nutrition for water grass. Because invisible water grass is growing slowly, it does not need too much fertilizer.

It is Key Step, start to place aquarium driftwood, we mainly use Rhododendron Roots. You can also use the Alders Root. Gentiana is a good choice as well!

Wood-putting finished, let’s see the aquascaping, don’t you feel so familiar? Many superiors also do this kind of aquarium landscape. It's easy to learn for the beginner.

There's a certain amount of attention to the water plant, the Java Fern should be placed at the back or the highest position of the landscape, there's no need to plant Java Fern in the water plant mud. Stick Moss on Rhododendron Root and directly planted Anubias Nana into the stone.

The entire landscape has been completed. When adding water, you must pay attention to laying a plastic film on the bottom of the fish tank to allow the water flowing from the film. So that the fish tank bottom will not be washed away, otherwise, the entire landscape will be damaged.

Riccia fluitans and Glossostigma elatinoides are the two most common varieties in the aquatic plant world, and they are the species that people prefer more when they choose to plant water grass.

When breeding such kinds of aquatic plant species, in addition to scientific and reasonable care, but also regular trimming. Cut off the aging and rotten leaves, so that the new leaves can grow normally, and let the water plant always maintain a beautiful and tough status.

For Glossostigma elatinoides, it is like a green velvet carpet, and the emerald green luster can always amaze people's eyes as if people are sloping on the green grassland, breathing the fragrance of green grass.

It is not easy to maintain the whole area of Glossostigma elatinoides. When the Glossostigma elatinoides grow too dense, the lower grass will rot and rot because they cannot reach the light. So the method of trimming the Glossostigma elatinoides is that When the growth is too dense, the leaves should be trimmed directly from the top, and the new leaves will grow back after trimming.

This kind of trimming method depends on the environmental conditions and the frequency of trimming times. But the maximum is 2-3 times. After multiple trimming, the new leaves will no longer grow, or the leaves become smaller. At this time, it needs to be replanted.

Riccia fluitans is like an elf in the water. Bubbles will pop up from the end of the leaf, like a layer of crystal clear pearl, dazzling and charming. Makes people fascinated in looking at it.

Riccia fluitans is a rootless aquatic plant, which needs to be fixed with plastic net or cotton thread when planting. And when it reaches a thickness, if without trimming, it will float to the surface like a cloud.

Since Riccia fluitans produces many oxygen bubbles during photosynthesis, it will increase the buoyancy of aquatic plants. The water plants at the bottom will also turn wither-yellow or even rot because they cannot reach the light; When the buoyancy is too strong, the water plants will float to the water surface.

So when trimming, we can use thinning methods, just like trimming the hair to make multiple layers. Trimming with water grass scissors at an oblique angle, only trim a part of the water grass, and the top growth parts could not completely be trimmed or destroyed.

Here I recommend this kind of tools: Plants Aquascaping Tools Kit

This kind of trimming does less damage to the moss, and the water grass recovers faster.

Different species of aquarium plant mesh have differences when trimming. We can make effective trimming methods according to the specific form of the water plant and the specific setting of the planted tank, so that the water plant can also fully show its beauty and toughness.

Physiological Injury of Aquatic Plants

1. Insufficient Light

During the growth, due to insufficient light, the photosynthetic intensity of aquatic plants will be reduced, the normal growth and development will also be affected.

For example, red water plants such as Ammania gracilis and Rotala macranda, due to insufficient light, the anthocyanins in the leaves will decrease; while chlorophyll will increase, and then gradually become green. In the case of insufficient light, it also shows yellowing, plant slim and fragile, and abnormal growth.

If it is placed under sufficient light, the water plants will slowly return to normal, and the leaf color will turn green, the red water plants will become bright red and dazzling. Therefore, it is necessary to strengthen the light to avoid light lack that affects the normal growth of plants.We provide fish tank led light online shopping  ,RFQ today.

2. Water Temperature (Too High or Too Low)

When the water temperature of the fish tank is too high, the leaves or young parts of the aquatic plants will be damaged, and the phenomenon of fallen leaves or yellowing will occur. Finally, the leaves will easily rot and dissolve.

When the temperature is too low, it will affect the growth and development of most tropical or subtropical aquatic plants. For example, the metabolic function of the plant reduced, and the growth is stagnated. Sometimes necrosis, rotten roots and other symptoms will also occur in the whole plant or part of it.

Here we suggest that better use a thermometer to keep daily accurate data.

3. Phyto Dehydration

Dehydration of aquatic plants is a physiological phenomenon (burning branches), which is mainly caused by excessive fertilization.

Since the total ion concentration in the water is higher than that in the aquatic plants, osmosis occurs, leading to the phenomenon of shrinkage. When it is slight, the leaf shape becomes small, and the young leaves do not curl or stretch; if severe, the whole plant leaves will fall off, and gradually rot, finally die.

Bio-mechanical Injury of Aquatic Plants

1. Snail Animals Injury

Mollusks such as snails are the helper to remove algae from the water tank, but sometimes they also endanger aquatic plants to supplement food sources.

Injured aquatic plants, leaves, and stems are incomplete, which will often affect the ornamental effect. In addition, the injured area is also susceptible to bacterial infection. The only solution is to remove the snails quickly.

2. Fish Damage

Some species of tropical fish use waterweed as a source of food in their place of origin. Nowadays it is raised as an ornamental fish, although it is fed with artificial feed, it still cannot change the habit of eating water grass.

Therefore, avoid raising herbivorous fishes such as tinfoil barb and Eyespot pufferfish in the water tank. Some fish, such as the Clown Loach, do not eat water plants, but they have the habit of digging holes, so they also hurt the roots of aquatic plants.

5. Carbon dioxide should be increased after trimming

Carbon dioxide is the material basis for photosynthesis of aquatic plants and protects aquatic plants under strong light. After trimming, on the one hand, the lighting of the water grass is suddenly improved (the lamps have not changed, but the occlusion has been reduced, which is equivalent to increasing the lighting intensity). On the other hand, the carbohydrates required to repair the wound are also in short supply.

If the supply of carbon dioxide is insufficient at this time, the water grass may be burned by strong light, and it may be infected by bacteria due to long-term non-healing wounds. Therefore, after the large trimming, be generous with carbon dioxide. Rather waste some than don't give less.

Here I recommend these kinds of tools: Co2 Balance Control

6. After trimming, the amount of liquid fertilizer should be temporarily reduced

Because the stems and leaves of aquatic plants are cut, many wounds appeared. These wounds will not only lose valuable carbon dioxide and nutrients but may also be infected with bacteria or viruses, causing plant disease or even death. At this point, the plants will focus all their energy on repairing the wound. At this stage, the plant basically stops growing.

After the injury, the plant's metabolism is significantly slower, and it takes a period of repair to restore the original growth rate. Therefore, the demand for fertilizer on aquatic plants will decrease at this time. In addition, after trimming, the absolute number of aquatic grass has also been greatly reduced. If still using the original fertilization dose, it is probable the fertilizer will not be used up and it will accumulate thus cause algae.

In a word, it is best to adjust the liquid fertilizer to a smaller dose after trimming, which can even be halved. After the water grass grows new shoots, no tiny bubbles appear on the cross-section, it means that the plant wound has been repaired, and then the amount of liquid fertilizer can be gradually increased.

7. Filters should not be cleaned on the day of trimming

When trimming, it is unavoidable to move the base of the fish tank (most common in weeding, planting grass, changing landscape, etc.), even if the tank doesn't become dusty, the water may become muddy.

In addition to changing the water at this time, some people also want to clean the filter by the way, but sometimes, too diligent is not necessarily a good thing, often, the fish and shrimp die after cleaning the filter.

This is because a large number of toxic substances such as nitrite and ammonia are released after churned the substrate. Usually, these toxic substances will be processed by nitrifying bacteria into relatively harmless nitrates and ammonium.

However, if the filter is cleaned at the same time, the consequence of the loss of a large number of nitrifying bacteria is that...... the toxic substances cannot be effectively processed, and those will have deadly effects on the creature.

So, the correct way is to wait for one or two days before cleaning the filter. Use the original tank water when washing, and do not wash it too clean. If there is a pre-filter, it is simpler. Just replace all the pre-filters material.

8. Best to Largely change the water on the trimming day

Water change is the best way to remove toxic and harmful substances in the water. The effect is immediate. After trimming the aquatic plants, make a large water change whether or not the substrate is moved in order to prevent algae outbreaks, or fish and shrimp outbreaks.

However, when adding water into the tank, take care that must not let the water flow directly impact the tank substrate, otherwise, it will not only easily damage the original landscape, but also may lead to a large number of toxic substances (such as hydrogen sulfide) releasing into the water that poison shrimp, snails or relatively fragile fishes (such as Dwarf sucking catfish, Siamese algae eater, etc).

How much water to change depends on the quality of the local tap water. If the water quality is good, you can change it more often, half or even two-thirds at a time. If the water quality is poor (tap water has a high hardness or pH value) and needs to be mixed with pure water, it is recommended to exchange only a third or a quarter at a time.
