OK my question is related to how fast water can flow past bacteria or should be flowing past living bacteria on bio-media in a wet and dry trickle filter. For optimal biological action.
I know as a rule, people look at tank volume and then look at turning that volume of water up to six time through the filtration media. So if tank holds 100 gallons it would have a pump running up to 600 gallons an hour.
However is there not an optimal rate, when looking at certain brand filters for example canister filters they do not all have huge flow rates some only 500 gallons per hour.
