I'd use a power filter simply because it better fits into my budget, but a canister is also a great choice. Skip the UGF
though, they are essentially just outdated waste traps and a power filter or canister will be much better for you. The Aquaclear 200 will probably be ok but I personally would have picked the AC
300 instead, as I like to turn my water over about 10 times per hour if possible (the 300 wouldn't do this either, but the next size up is the 500 and that would just be overkill). Or if you want you could add a second AC
200 for a total of 400 gph
, but it wouldn't really be necessary I'm sure, just a personal preference of mine.
