A good ATO for a Nano

johnny4491 · Apr 10, 2017

Anyone know of any good ones out there I suck at looking things up

I use an Avast Marine ATO on a 45 nano. It's easy and very reliable. Uses a pressure switch instead of optical sensors or float switches which can get messed up from the salt (I've had it happen to a Tunze).
Other options: Micro ATO, Tunze Nano Osmolator, anything with precision is what you need, so it stops filling when it's supposed to and doesn't overfill or underfill, since your nano needs stability. I vote for the Avast. Easy and really precise, takes about 3 minutes to connect it.

Ok because I have a 6 gallon nano so you still think the Avast is the best option

Smart ATO or the Micro depending on the size of your tank

definitively the micro on a 6 gallon

Oh, 6 gallon. NM. Gargamell is right, I'd go with micro ATO on that size tank. That's a pico tank! o_O

I have just the single with a bracket.

My top off is just one gallon so not that much of an issue if it overflows. But if your concerned with single float failure then look at the double nano upper and get two brackets. You can always call the guy and ask. That's what I did both times. He was very helpful.
