My boyfriend is helping me get a new aquarium for christmas. Tis a standard 75 gallon with stand. I was wondering what is the opinion of the SunSun Filter line? I'm looking at two of these for it because I filter for double the aquarium gallons. I'm also trying to keep costs down. Thanks for your help! SunSun HW-302 3-Stage External Canister Filter, 264 gph and what brand/model of filter pads does it use?
