creepyoldguy;4424807; said:I have to agree that one AC110 would be sufficient on a 55g. They move more water than an xp2 and hold a fair amount of media. A lot of ppl on this seem to overkill filtration (which is not a bad thing), but for your average stock in a 55g, the AC110 would be plenty. Just keep up on your water changes and you should have crystal clear water. I personally use AC110's and Rena canisters (2 xp4's to be exact). In my experience, they do their job well, but for a 55g, just save some $$ and get the 110. With the extra money you save you can adjust the media to fit your needs. Good luck. What are you stocking with anyway?
thats what im thinkin. and right now, its gunna be a clown pleco, tiger oscar and fenale GT
