Great product from Tunze, no surprise there. By Andrew on 11/2/2013

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!

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

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

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

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.
BulkReefSupply offers great customer service and support.
Easy and high quality By Chris on 6/6/2013

Although pricey, this system includes everything you need to safely and easily automate top offs, minus a reservoir. The builtin safety features keep your tank from overflowing or constantly running the pump in an empty reservoir.
Very nice little nano ATO By tim on 6/3/2013

Small...perfect for nanos. Not all the bells a whistles as the full version, but for a nano, you can't beat it. Solid product, very strong magnets.
Great for a 45 gallon tank with 15 gallon sump By Butters17 on 5/24/2013

Ive been using this product for about 6 months now. Has not failed me yet. This is a must have for saltwater tanks, keeps water levels/salinity the same. my only regret is not getting this sooner..
When i eventually get a larger tank ill get the bigger tunze osmolator for sure.
awesome By ReefDVMs on 5/13/2013
