Backwash and Flow Rates of Filter Media – Pure Water

If you want a greater service flow rate, the best solution is to install two 10" filters side by side. This gives you a healthy and effective 4.5 gallon service rate. You set the timers on the filters so that they backwash at different times, then you have an adequate backwash potential of six gallons for each filter.

7 Ways To Reduce The Water Flow of Aquarium Filter Fish

The idea is the high flow rate stirs up solid debris and brings in into the filter media instead of the gravel. This prevents sludge buildup and maintains water clarity. Aquarium filters with higher flow rates often use larger filter cartridges or have more room for lose filter media like activate carbon, phosphate remover and foam pads.
