How to use fish tank filter cotton correctly!

Fish tank filter cotton is generally the filtering material in the aquarium filtration system and is the main material for physical filtration. Physical filtration is the process of using a water pump to draw water from a fish tank into a filtration tank, allowing the water to pass through filtering materials such as filter cotton in the tank, removing large particles and impurities from the water. Physical filtration cannot remove small molecule substances (bacteria, algae, etc.) In water, filter materials need to be cleaned or replaced regularly.

What are the main filtering layers of a fish tank?

There are four main filtering layers.

1. Fish tank filter cotton: Physical filtration, blocking large particle waste and absorbing some bacterial metabolic waste.

2. Biochemical cotton: Its main function is to improve the clarity of water quality by cultivating nitrifying bacteria that decompose organic matter.

3. Ceramic ring: Its main function is to attach nitrifying bacteria, making water healthy and non-toxic. To enhance the effectiveness, bacterial rooms can also be placed simultaneously.

4. Activated carbon: I believe everyone is familiar with this. It is mainly used to adsorb the decomposition products of organic matter in water, but the usage time is not long and can only be used for a specific period of time. It can only be reused after a few months of use.

How to put fish tank filter cotton?

Firstly, regular fish tank filter cotton should be placed on top, as it can effectively filter out some large impurities when water passes through. But you can put two layers of filter cotton, because if the top layer is not clean, it can be cleaned. But it can be cleaned during cleaning to avoid damaging nitrifying bacteria with excessive force. Then the second layer is made of bio cotton. The next step is to add ceramic rings, but in order to improve water quality and maintain it, more can be added, which can occupy 3% -5% of the entire water body. As for activated carbon, if the water quality is healthy, it is not needed when there is a fishy smell in the water.
