I want to lay the bottom sand for the reef tank, should I use coarse or fine sand?

Hello, I think it's best to use coarse sand to lay the bottom of the reef tank, because coarse sand is not easy to turn the sand up due to the movement of fish, and coarse sand is also convenient for cleaning fish feces and other garbage.

When it comes to laying bottom sand for reef tanks, you may be faced with two options: coarse sand and fine sand. Each type has its own advantages and disadvantages.

Coarse sand usually has larger grains, so it can provide a better habitat, hiding place and filtration system for corals. At the same time, coarse sand can also help maintain stable water quality, as they can provide more places for biome and bacteria to grow.

However, coarse sand also has some potential problems. They can cause stress to corals, especially in environments with strong currents. Coarse sand can also make the current too strong, which can be detrimental to the growth and survival of corals.

Fine sand can provide a smoother surface, which may be more attractive to some corals. They may also provide a better environment for corals to grow, as they provide more stability and support to corals.

However, fine sands may not provide enough hiding place and filtration systems because they have smaller particles. This may also affect biodiversity and water quality stability.

When choosing, consider factors such as your coral type, current intensity, tank size, and water quality. You can also consider mixing the two types of sand for the best results. The best course of action is to consult with a professional or aquarium specialist who can provide the best advice for your specific situation.

Coral sand for the bottom sand of the sea tank. Coral sand occupies a very important position in an aquarium, it is not only an ornament, it also has the function of "biochemical filtration".

It is a mistake to think that the whiter and more detailed the "bottom sand" at the bottom of the aquarium, the better it looks, because a lot of white coral sand is bleached, and the fine coral sand will affect the filtration effect, so that the dirt in the aquarium accumulates in the bottom sand layer.

Because it is too small, the sand itself lacks capillary pores, and cannot cultivate a large number of "nitrifying bacteria", so that the toxic substances in the aquarium cannot be completely decomposed, which is harmful to aquariums, so larger coral sand should be used as the bottom sand.

Importance. Generally speaking, it can be divided into thin bottom sand and thick bottom sand, as we all know that once there is a sand layer in the tank, after a period of normal operation, the aerobic zone of the surface layer of the gravel and the micro-oxygen zone of the middle layer are established.

In the anaerobic zone at the bottom layer, aerobic bacteria - nitrifying bacteria and anaerobic bacteria - nitrogen bacteria will produce hydrogen sulfide (H2S) and biogas (CH4) in the anaerobic zone of the black bottom layer, which are substances that are extremely toxic to living organisms, but fortunately, these gases are transformed by some other bacteria in the process of rising, and at the same time combine with some heavy metals, and are basically non-toxic when they reach the water surface.

We can often see bubbles coming out of the sand layer, if the bottom sand is set properly, these gases are actually CO2 and O2 produced by algae attached to the sand, otherwise there will be some CH4, H2S gas, these toxic substances will bring a lot of disadvantages to organisms, directly lead to illness. So there is still a big trick to the application of coral sand, and of course we all hope that coral sand can bring greater benefits to our aquarium.

Summary. Coral sand for the bottom sand of the sea tank. Coral sand occupies a very important position in an aquarium.

Coral sand for the bottom sand of the sea tank. Coral sand occupies a very important position in an aquarium.

Different tropical fish need different bottom sand, here I will first introduce several common stones for fish tanks: 1 Pebbles I believe everyone knows, that is, those small round stones, pebbles are gradually formed by long-term erosion of mountain stones. The surface is smooth and colorful.

Among them, Nanjing Yuhua Stone (also a kind of pebble) is more famous in the world. It is suitable for small and medium-sized fish tanks, and small stones are also suitable as bottom sand. 2 Taihu Stone I believe that everyone should know what kind of stone it is, even if you don't see its shadow and hear it.

Whether it is an aquarium or a landscaping, it is a rare stone, Taihu Lake stone with Jianyi should be used for some large aquarium landscaping, planting some large-scale cultivation and flushing water plants, can form a very beautiful landscape. <>

<> whether to lay sand or not in the reef tank is a different choice for marine fish breeders. People with filial piety are afraid of trouble, and feel that laying the bottom sand is not only troublesome to take care of, but also easy to cause the fragility of the ecosystem in the tank. Poor treatment of bottom sand will accumulate harmful substances, increase NO3, accumulate nutrients, increase hidden dangers, and is not conducive to the survival of fish.

Some people like to lay the bottom sand, thinking that the bottom sand is not only beautiful, can help fix the living stone, but also has the function of "biochemical filtration", providing a natural biological chain system for the fish. It also helps to cultivate microorganisms that provide food for corals and sinks. Therefore, the key to the selection of whether the reef tank is suitable for laying the bottom sand lies in whether the bottom sand is suitable or not.

There have been senior players on the forum who have said that the method of laying sand at the bottom of the reef tank is mainly 3cm thin residual sand, sand turning organisms and sufficient water flow. Below I will add some of my own understanding, and then say it specifically, if there is a misunderstanding, please correct it, don't let me let me laugh at the <> of the generous house

If you raise grass with special mud for weeds If you raise fish, it is recommended not to use sand He pollutes the water quality, and the feces are not easy to filter and sink in the sand, so it is best not to use sand, and it is best to raise fish in a clean tank.

As the saying goes, fish farming first raises water, it can be seen the importance of water, if you want to raise water, you must first ensure the quality of water, generally in indoor koi fish are used in tap water, but for koi fish.

To grow healthily, filter media is indispensable, and there are many kinds of filter materials in koi fish tanks, and sometimes they will be entangled in whether to put them in the end. Then here's the problem! Do koi fish tanks filter coral sand?

There is no hurry to talk about the question of 'koi fish tank filtration and coral sand', first of all, let's understand the composition elements of coral sand and the role of filtration: coral sand is mainly composed of shell fragments or coral, and coral sand has the ability to continuously release calcium carbonate.

It contains alkaline substances, and the pH value of the water quality will change when the water flows through the filter material coral sand, because it will continuously release calcium ions and magnesium ions to provide high hardness and stable pH for the water quality of koi culture.

Coral sand varies in particle size and size, and coral sand is rich in micropores, which can allow a large number of nitrifying bacteria.

To survive, and for koi fish to survive, nitrifying bacteria are indispensable. Generally, it needs to be replaced before and after 10 months of use, and the filter media is laid in the lower layer.

What to put in the koi fish tank filtration, the filter materials that can be selected are: filter cotton, biochemical cotton, and maifan stone.

Ceramic rings, glass rings, zeolite.

Biochemical balls, activated carbon.

Volcanic rock, coral sand, bacterial houses, quartz balls, etc., a powerful filter is often composed of many small molecules, and these filter materials are fine molecules. A powerful filtration must have non-stop moving pinions, and these pinions are the necessary filter material, although they are inconspicuous separately, but the synthesis is a powerful force.
