I have built my 550 gallon aquarium I need to know how much filtration is needed I have two custom built canister filters with two 900 gph pumps that gives me 1800 gph I've researched and there are several places that say 2cs 4xs 6cs of water how much do you guys think I need or will the 1800goh...
I have ones where the ph gh kh and temperatures are very very close. I just haven't researched the temperament of all of them trying to take a shortcut by asking
