I am looking to get an ATO for my 85 gallon. I've always manually topped off twice a day, and done fine with that, but would like to get one set up so it will be taken care of if I go out of town. (I used to have my tank at my office and had staff that took care of it in my absence). Anyway, I am looking at the tunze and the duetto 2. I know people really praise the tunze and can't find much in the way of reviews on the duetto 2. I like that both setups have two different sensor mechanisms in case the first one fails. Any suggestions?
