Love this little ATO system, and it's affordable for a Tunze product! I've had it for a week and it has been absolutely reliable with no fluctuation in my water level. My sump is a 10g aquarium with a heater, skimmer, and return pump all packed in, so it is a tight fit but it works. I left the cardboard separator between the two magnets because I had read that the magnets being too close can interfere with the float valve. It works like a charm and I couldn't be happier! Best $100 I have spent on my aquarium so far!

Tunze has a great product here! It has been working flawlessly to keep my tank topped up and my levels much more stable. It's really one of the most essential pieces of equipment you can buy, it's well made, but my only gripe is the quick connect from the pump to the controller itself. I'd prefer something a bit more salt creep proof! But overall, I'll be buying another one for my next tank as well!

installed this ATO on my 28 gal.nano cube.so far it's working great.now my cheap protein skimmer works a lot better because of the constant water level.pump's a little loud so I suspended just above bottom of container and now it's quiet.doing great so far.

After avoiding a couple of floods when i first hooked it up, i think i finally have it dialed in. If the glass on where you are placing it, make sure to use a spacer, as the magnet affects the float. directions could be clearer about this. after I got it going correctly, i love it.

Installed this ATO on a Biocube 29. I had a little bit of an issue with the pump not shutting off properly after my initial install. After a short conversation with Tunze customer service we determined the switch was being interfered with by the magnet from my Tunze 9002 skimmer. I moved the switch to the other side of the return chamber away from the skimmer magnet, and it works like a charm!

Best ATO purchase By Oscar on 11/26/2013

I love this ATO easy to put anywhere either in sump or in your tank. I love that it had magnets not suction cups that easily fall of and can dump water into your sump. I also, love that it includes its own pump without the need to purchase one and the replacement its cheap aswell.
