Is it OK for Arowana to filter with volcanic rock and coral bone

If you want to choose filter materials, it is recommended to choose the fish fun honeycomb bacteria house, volcanic rock and coral bones are best not to be put to prevent the arowana from scratching the fish body in the process of swimming, causing unnecessary losses.

Bacteria houses are generally used, and I have never heard of using volcanic rock and coral.

In fact, the purpose of using filter media is to purify water quality and cultivate digestive bacteria, and establish a strong and stable digestive system, so follow the above two points in the selection of filter media to choose the right filter material.

According to the Arowana tank filtration system, the current mainstream bottom tank filtration is taken as an example.

Generally, the bottom cylinder filtration is divided into four grids:

First of all, let's talk about the wet and dry separation box. The drain is best made into a U-shaped rain shower pipe, so that the water will be more uniform, the water sound will be smaller, the rain pipe is linked to the dry and wet separation box, the so-called dry and wet separation is the physical filtration refers to the filter cotton is raised, so that it leaves the water surface of a filtration method. The guiding ideology of dry and wet separation filtration is:

Do not allow food residues and feces to be immersed in water for a long time and pollute the water quality twice. The filter material needed here is white cotton, white cotton is placed in the dry and wet separation box, and the white cotton in the box is usually spread with 3-5 layers to filter impurities, and the top layers of white cotton are selected from ordinary white cotton, such as the white cotton in rolls of faith, which can be cleaned every three days and replaced with a new one in about half a month. The bottom layer chooses the most delicate white cotton, such as the German JBL cashmere cotton or the blue magic cotton of Most, although the price of these two white cotton is more expensive, but the filtration is more delicate, and it can be cleaned and used many times, and the cost performance is still very high.

The combination of ordinary white cotton and quality white cotton can be selected according to the actual situation. Submit.

Bad Coral sand is good for increasing the hardness of water quality Suitable for monk fish.

It is no problem to put an appropriate amount of coral bones, but if there are too many of them, the water will be alkaline, and the origin of Arowana is weakly acidic, and the pH value of the water is maintained.

**The volcanic rocks on the rock are mostly fake, and the severed coral bones can play a role in hardening the water quality and acting as a bacterial house, which is beneficial.

Yes, turtles can perch on it.

You've done it all, but it's not necessary, you're a novice at first glance, and you're still in the state of mind that it's good to get all kinds of things done.

Ceramic rings, biochemical seeking, bacterial houses, volcanic rocks, are all similar things, js fools novices, you don't have to buy such a complicated one in the future, just one, volcanic rock and coral sand hard water, don't buy it in the future. Biochemical cotton has the same effect.

Start at the inlet - filter cotton (put two more layers) - ceramic ring, biochemical seeker, bacterial house, volcanic rock casually, biochemical cotton on the back of the filter cotton, the position is arbitrary.

Do not put activated carbon, unless the water has a peculiar smell, do not put it, and do not put it for more than 1 month.

The filter material does not need to be so cumbersome The white-faced fungus house is enough I don't need to say it before and after Especially don't put activated carbon It's not good It's too expensive The bottom filter and release the biochemical ball is equivalent to the lack of heart eye Magnetic ring Coral bone Volcano is not as good as the fungus house.
