How soon can you filter all the water in an aquarium filter?
Estimation of 5-8cm keep 10 goldfish are a bit. The pump of the filter barrel is only 3W, and the water circulation is obviously insufficient. In theory, CY-20 water flow is about 200L/ hours, your entire cylinder volume is 80L, about half an hour can filter the water in the cylinder again. But this is only theory, first, the pump affected by water level
The original basic sponge can not replace the glass ring, said that life is about 2 years, but the glass ring I used more than 2 years is no need to replace the new net, should.
As for cleaning and filtration, there is no need to operate regularly. As long as the water flows smoothly, you can basically leave him alone. If there are any signs of a poison race, remove the filter cotton and ceramic rings and clean them with water from the tank. They must not be washed with tap water, nor can they be made with soap, detergent or the like.
Under normal circumstances, manufacturers recommend some exaggeration, and Louzhu cylinder has exceeded the recommended range of manufacturers. Other filtering methods are strongly recommended.
Landlord with CY-20 camel 50cm cylinder too reluctantly, if it is grass cylinder, raising micro fish almost.
