Help me pick an ATO

james983 · Jan 15, 2015

After years of manually topping off my tank due to fear of a ATO failure I have decided to find the best ATO available. There are so many brands I am lost. Obviously they all claim to be the best and most reliable but I would like to hear from fellow reefers.

I'm looking for the most reliable unit out there. I do have an Apex so using that with a Breakout Box is also an option. The other issue I have is the water tank is about 20 feet from sump. Any opinions are appreciated.

Neptune DOS and a switch. They were even working on an optical sensor, should be out in the next couple months

Or regular BRS pump and float switch

Given the distance I agree with jduck and go with the Neptune Systems Dos and some float switches

Unless you can find a different pump that can go the distance then go with the innovative marine ATO i really like the sensors they uses, i have had the unit for over a year and never once a problem, Or just use the apex breakout box with with float switches

SpectraPure Ultra-Precise Auto Top Off

This is what I use - I am topping of from the basement to the first floor of the house with NO issues.

Spectrapure UPLC-II, the best on the market today. Mine is mounted next to the sump in my stand but the ATO storage and RO/DI are in my garage 35 feet away.
