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.

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.

works flawlessly. Only regret is not getting the bigger model with two sensors. the 5 second time out feature is great piece of mind however.

No issues so far. I installed this in an 8-gallon tank so I am especially happy for the auto-cutoff. Seems pretty solid!

I purchased this nano because I was so happy with the 3155. May of this year.
It never really worked like it should, it had an electrical problem right away but I thought I could live with it until just stopped a few days ago. My hubby checked the electrical current and it did not have one.
So I am now purchasing the 3155 to replace this one. If you are trying to decide which one to go with. I HIGHLY recommend the 3155 even though it is more expensive. I wish I had.
