The tank with two filtered water is not clear
Limpets except wall algae effect is the best, but I'm not familiar with the money, do not know whether to eat.
The wall is not very clean, if it is basically useless with moss scavenger. Artificial wipe, filter barrels, after a series of UV lamp, algae suppression can be better.
The 1200 is a barrel Chuangxing filter 32W. The other one is 23W's submersible pump. Do you have a filter cartridge?
