so i have some canister filters that im not impressed by there gph flow. on 3 of them so far ive taken the motors out completely. hook up canister like normal on the tank and have hooked up rio powerheads instead. flow increased 4 fold. only question is water flowing through the chambers inside the canister too fast be bad? throught the pads i dont see a problem and should perform and catch debris as it should. its the bio im wondering about. any thoughts would be great. tanks are crystal clear now. i hate seeing debris float by an intake and see it not powerful enough to suck it up.
