Great product very reasonably priced By Randy on 5/30/2014

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.
Ok product, but be careful By Nano Pete on 11/26/2013

After almost flooding my basement twice and contacting Bulk reef supply; I was contacted by Tunze technician and he worked with me to fix my problems. When attaching switch with magnet onto sump glass the maget affects the switch if the glass is too thin. I needed to shim between the two magnets for the switch to work properly. Also, be aware of creating a siphon from reservior to were your supplying ATO water. As far as quality; You get what you pay for...
Pros- works as advertised.
Cons- doesnt come with clear instructions
Excellent ATO By Michael on 11/25/2013

I just installed this in a Nuvo 24 and it's working excellent to keep my water level exactly where I want it. The pump can fit right into a 5 gallon polyurethane jug without modification, which is really nice if you don't have a special RO Reservoir. It was easy to assemble and install and the pump is quiet enough to not bother my wife.
My only two complaints of this system: I wish the control box had tabs to mount with screws to the interior of my stand and I would love for the control box to have some kind of LED that either indicates the unit is powered or that the pump is on. I feel like for the price a single LED in the control box isn't a crazy expectation. Other than that it's an excellent product.
