Tunze ato is good but if you spend a little more, may you can get apex with io breakout box then you are set. Seriously, once you have a controller, it is so easy to take care of the tank. I would never a saltwater tank running without a controller.
I found with my float switches controlled by Apex controller, i can pump fresh water or new water to my tank with the exact amount.

The reason I love the tunze is because it doesn't use a float valve. I just totally destroyed my tunze ATO unit in a flood 2 days ago though (piece of plastic somehow plugged the outflow of my refugium... what a mess), so for my next tank I'll either have to buy a new one, or do something else. Can the apex work with an infrared sensor like the Tunze, or is your only option a float valve?
