ATO

[Matthew Cautero]

Best auto top off for a all in one Reef tank. I have a red sea 170 max thanks everyone

I use the smart ATO by coralvue and love it. Otherwise the tunze is a very good one.

I use the smart ato and love it. It has an alarm and is very accurate since my salinity is always stable.

The Tunze are pricey but well worth it.

I use the Tunze 3155 on one tank, and had been using a Autoaqua Smart ATO on the other, no complaints or issues with either. Just upgraded the Smart ATO to the AWC Touch for the ability to also do auto water changes. For the capability and cost my pick of the three is the AWC.

I use this one, and really like it [especially for the price!]

I've been looking at that one for my biocube16.. how long have you had it? Any trouble with the sensors not reading?

I've had it for about 1.5 years, never once had an issue with it performing [did have an issue when the tank-sitter was pulling around with cords and moved the sensors though -_-]

I've even tried "plugging them up" a bit to see what would happen, and I had snails all over my sump before moving to my current tank, and never a hiccup
