A Small External Filter?

[Nick Bramley]

Hi, I have a 30l UFO 350, it originally came with a UGF system which I quickly removed with a small internal filter but that isn't filtering my tank as well as I'd hoped and wondered if anyone had any suggestions on what I could do, thought about getting a small external filters but my knowledge of these is pretty limited

Any help would be greatly appreciated

Thanks

The Eden 501 is the smallest external filter I know.
For a similar price though you could get a classic Eheim

The fluval 105 is the smallest external filter i can think of. It is for tanks upto 100litres and i believe has a regulator so you can control the flow of water.

Edit: although the filter suggested above looks qute nifty
