The Tunze ATO on my setup quit working. The pump and float switch are fine. It's the circuit board, and it just constantly clicks. I need a new ATO as soon as possible. There are so many mixed reviews on all them. I'm sure it will be the same on this post as well, but I wanted to see if there would be a clear winner. I have a 90 gallon with a 29 gallon sump. What would you all suggest?
