I have 4 juvinile discus in a 20 gal quarantine tank with a tetra whisper 20 on it(petsmart box special). I am going tomorrow to get a biowheel 150 to help with filtration but my 60gal tank they will be going in has a biowheel 350 on it. I have thought of upgrading to a fluval or eheim canister filter. Would it be worth the upgrade or is the biowheel 350 good enough. It appears to move decent water but is very noisey.
