being that i have my tank decorated just how i want it, and my fish are doing quite well along with my tank and water quality. as i mentioned before i plan on upgrading to the 2-300 gallon range once i move. im looking into getting a canister filter. one that will handle around 250-300 gallons. this will originaly be applied to my 75 untill i upgrade. my biowheel 350 is doing fine but i want something that is REALLY going to make my water crystal clear. i was wondering if anyone might have any recomendations for a certain brand or type. i would like to keep this in the 150.00 range if possible. any companies i should stay away from. what features should i look for?
