Deciding on an ATO

[sas226]

hey folks, so I'm setting up a 80g system. I've narrowed down my choices between the Avast Marine ATO (with float valve) or Duetto Dual Sensor setup from XP aqua. I realize ideally the Tunze 3155 is the go to, but it's a little out of price range at the moment with the holidays and what not (the BRS sail will be over by the time I order.) so I'm trying to find the next best thing. I can't find a TON of info on the avast but what I have found has been positive. There's a decent amount of the Duetto but some people seem to have issues. Just looking for some advice. thanks

The best choice is the Tunze Osmolator 3155. If you want a cheaper option that is still good, use the Reef Breeders EXO.
