I had a super affordable Sun Sun UV filter for years and years and was very happy with it.
I found the UV was more useful for keeping algae from forming than for removing any free floating matter. But I did appreciate the fact I did not have any algae issues while using this filter.
The Sun Sun was under $100 . I forgot the exact model, but it was for a larger tank. I was also impressed that this was one of the few filters I’ve had that reliably primed itself after being turned off for any reason and it was quiet.
I got mine on Amazon, but they may carry them at independent pet stores.
