Ideal Flow Rate In Pond Filter

Water Pump
WATER FLOW RATE POND FILTER -- Flow rates are important for a few reasons. Firstly, it would be normal advice to filter the complete capacity of a pond around every 2 hours. This is the specification of the pump you are looking for. You will need a pump of around that flow rate after losses due to bends etc. Why is this important? It is simple and has two basic answers. Firstly the flow rate has a major effect on the biological capacity of the filter. These filters work using naturally grown nitrifying bacteria which help change noxious ammonia (liquid fish waste) into noxious nitrites, and finally into harmless nitrates .
