How to strengthen the physical filtration of fish tank

It is necessary to use a larger flow pump, and more water can pass through the filter material per unit time to enhance the function. For example, the flow rate of the filter is more than 8 times that of the fish tank, and it is very likely that all the yellow water and green water in the fish tank will be cleaned in an hour or two. However, if the efficiency of the filter is extremely low, it may take a day, and even the final cleaning will not be thorough.

The water quality of the fish tank is too turbid, so a small amount of water purifying agent can be used together. For the physical filtration system of fish tank, only three layers of white cotton, one layer of magic carpet and three layers of biochemical cotton are needed at most, which is completely sufficient. No matter how much it is put, it is simply unnecessary, but it will have a counterproductive effect on the water quality of the fish tank because of excessive siltation.

Several points for attention in cleaning fish tanks

1, don't use chemicals such as detergent to wash the tank, and the residual chemicals will easily affect the fish.

2. Don't wash the filter cotton when washing the cylinder.

Don't change a lot of water when washing the filter cotton.

4, don't use hard objects such as steel balls to wipe the old moss, which is easy to scratch the glass and damage the silica gel.

5. Do not thoroughly clean the fish tank at low water temperature (below 15℃) because the nitrification system and moss recover slowly.
