I have a new 80 gal bowfront tank and i have to buy a filter for it i perfer canisters. i have two fluvels one on my 55 and one on a 30 and they work quite well but i can get a hold of an ehiem for almost a lower price that a fluvel for the 80 which is better? and is there a better canister for this tank. Please bear in mind i have a 8 inch GT and a 7 inch Red devil, along with a 4 inch convict, 3 clown loaches and two plecos. I wanted to post this here because who knows strong filtration better than SA cichlid owners?
