Go Big Or Go Home !
Ok guys so i have 2 fluval 405 right now and im switching over to a sump this weekend, my question is should i leave the canister filters running so that i dont upset the biological filtration or will it be ok if i just take the rubble rock out of the canister fliters and place it in the sump with more live rock or base rock ??? Should i keep atleast one of the canister filters ???
