For a 90 gallon you already have a filter (XP3) fit for only auxiliary on a tank that size. I would not buy another aux type performer which is the Sunsun. In the engine world these stack-only filters are comparable to a V-tech 2.4. For a tank that size that is trying to tell you you need to step up to a higher performer the circumference FX5, comparable to a 5.7 Hemi engine.
I only want a cheap canister filter for now, it will probably get thrown on my 180g in the future as extra filtration. I don't want a FX5, i would spend my money on a sump. But the canister filter have to do, till I'm completely done downsizing (14 tanks- 7 tanks:cry

Back to the original question, what happened to the 303? Where can i get one with out a UV?
