Canisters are sealed unlike sumps and dont flood if the power is outI have never run a canister filter. I was always a fan of HOB incase something went wrong and you weren't home it would drain the tank all over your floor but I think I'm gonna try this
1x FX6 won't beat those 3 but it's not bad at all, you would need 2x FX6 to get rid of those 3x 400, if you have extra money then I would say get 2x fx6 instead a single oneI'm not even sure the fx6 alone would work as well as these 3
Three fx's would be best... I have two on my tank (210) now and will be adding a third (bought @petsmart for 170.00)I have a 210g tank with Central and SA cichlids. I run 3 emporer 400's and it does a good job but would a single fx6 work better? Black Friday at PetSmart has them for $170. I couldn't pass it up
