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.

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.
Perfect for my Nano tank By MICKEY on 10/7/2013

No issues so far. I installed this in an 8-gallon tank so I am especially happy for the auto-cutoff. Seems pretty solid!
upgrade By Red Fish on 10/4/2013

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.
Nano ATO jury still out By RikerBear on 9/26/2013

I bought two of these for my nano reef and for my FOWLR. The one for the nano works great...thenone on the FOWLR sticks and won't always activate (pump not float sensor).
I ordered a replacement pump, so we shall see how it works

I purchased this to complete my nano set up. I have a 24 gallon Nuvo by IM and this ATO compliments it well. I installed last night in about 15 minutes. Worked well when I tested it. It fits great in the back chamber.
One of the best additions to my tank! By Paul on 8/8/2013
Paul would recommend this product to a friend
Definitely one of the best additions to my tank so far. It was easy to set up, and I haven't had any issues with it yet. Throw the pump in a container with RO/DI, set the float where you want it, plug it in, and away you go. Water level is staying constant and salinity is stable. It's great! Going to eventually upgrade to the 3155 and use this for my QT/HT.
Does what it needs to do! By Brett on 8/5/2013
Brett would recommend this product to a friend
Installation was simple and easy to understand. Strong little pump. Has no problem pushing the water from the bottom of my stand to the top of the tank (JBJ 28 Gallon Nano Cube w/stand).
Working great. The magnetic mounting system is fantastic. By Arabo on 7/24/2013
Arabo would recommend this product to a friend
I bought this system to pump some distilled water from a 5 gallon water tank to a container that is about 10ft above. The pump was a bit too large to fit into the 5 gallon tank and I had to use a smaller submersible pump but the magnetic mounting system for the float valve alone was worth buying it.
