Is there any reason that you couldn't run a uv sterilizer without mechanical filtration? My aio makes me give up one of the 2 overflows for a uv sterilizer. The included sponge filter on top of it clogs within days. It's all particulate matter, nothing that would impede the flow of the sterilizer itself. Any reason I couldn't run it without the sponge, and rely on my sock in the other overflow chamber for mechanical filtration?
