Ato

[manitou74]

I have a DIY auto top off that has become unreliable. What are recommendations for ATO?

I have one from autotopoff.com that works very well. I bought it used and have been using it for several years. They're simple, cheap and reliable. Tunze ATOs seem to have a very good reputation too, but they're pretty expensive.

I have a acrylic 10 gal tank with a fitting in the side and a float valve and let gravity do its thing
