Which Type Of Aquarium Filter Is Best For Luohan?

Q. I have just bought a two-feet-long aquarium and two luohans. The filter I am using is a power head pump and it doesn’t seem to be able to get rid of all the waste products. Can you recommend a pump that will work more effectively?

The standard filter can only perform the basic function of filtering dirt onto the cotton wool, and does not have a filter mat for enough waste-eliminating bacteria to grow.

A standard filter for a two feet tank is usually only 10 per cent of its size, and is not powerful enough to totally eliminate waste. For it to work effectively, the filter should ideally be at least 30 per cent of the tank size.

It would be rather difficult for a standard pump to suck all the dirt, unless the water is directed to circulate below it. If you are using such a pump, you may have to remove the dirt manually with the help of a net, once in a while. A more powerful pump will not necessarily be more effective. In fact, a slower pump could be more conducive for waste-eliminating bacteria to do the work of cleaning up the tank.

Placing some stones or coral chips on the bottom of the tank may help. However, it is very important that you use a net to remove the dirt occasionally. Some hobbyists use an under-gravel filter that is placed beneath the stones on the tank floor. This is another way to keep the water clear. However, if the dirt that has accumulated beneath these stones is not properly and regularly cleared, the water condition becomes unhealthy and this may lead to the fish being infected with diseases.

Here are some internal filters you might want to consider for your Luohans’ home.
