ATO for 20L suggestions

[James5214]

So I'm looking to invest into a ATO and what to know what you guys use or if you would of got something different than you have now. I only have a 20 long and don't need to go crazy over board on pricing. Let me know what you guys are thinking. Thanks

A Tunze Nano Osmolator ATO should work fine on a tank your size. Good luck!
