One meter bottom filter and three filter tanks, how to put the filter equipment best? Why is the filtered cotton mixed after washing once?
The first stage: put fiber cotton in the physical filtration stage (note: socks can be put on the outlet of the water outlet to filter out suspended solids, which is convenient for cleaning).
The second stage: the chemical filtration stage contains chemical adsorption filter materials such as activated carbon, ammonia-absorbing stone, zeolite and clear water resin (note: the adsorption effect of this kind of filter materials is generally only three months, so it must be replaced).
The third stage: the first stage of biological filtration is to place biochemical cotton (note: it is best to choose the one with suitable pore size, high strength and great elasticity).
The fourth stage: the second stage of biological filtration is to place porcelain rings (note: the higher the water absorption of porcelain rings, the better the surface roughness)
The fifth stage: the fourth stage of biological filtration is to place biochemical balls (note: the capacity of this stage should be large, and the number of biochemical balls should be as large as possible, but drip filtration should be used as far as possible)
The sixth stage: the submersible pump is put into the water balance box, and the filtered water is transported back to the fish tank. The first level can be combined with the second level, and the third level can be combined with the fourth level according to the space situation.
It is normal to wash the filtered cotton once and mix it. The deposits in filter tanks and pipelines are caused by water scouring. Just cycle for a few hours, don't worry too much.
