I use a Rena canister filter on my 20 gallon aquarium. I use bio chem zorb in the canister. The directions say to rinse the bag before putting it into the canister. I was wondering how long i am suppose to rinse it for? i dotn want to it rinse it for too long and waste it. The directions say to rinse, until it clears, but form my experience it has never even come close to clearing. Just wondering if someone else uses this type and can help me out?
