At the moment I'm running an internal filter on my 37gal planted. While it's gph
is rated strongly enough for it I'm not entirely convinced how efficient it is, so I'm looking into getting a canister.
At the moment I'm looking at SunSun HW-302s. So far any reviews I've found online have given positive feedback, but I'd still like to know what other options are around I guess.
Being a student I'm fairly restrained by price. I haven't looked at my LFS
yet, but that's on the to do list. So in general I'd just be interested in some discussion of some more affordable canisters
