when i was in vietnam, i went to a couple of lfs there and saw this canister filter, atman uf2400. it has built in uv, 22L media volume, use 42w and flowrate of 2340l/h. i picked one up just for the heck of it cause it was really cheap, $80usd. have yet to set it up but was thinking of putting it in my 100g datnoid tank once i set it up. has anyone heard of this brand?
