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

Budget Friendly By Victor D on 4/30/2013

More than enough for my 29g Biocube
Easy to set up (Except the tube for the pump)
Only runs for 1.8 seconds but can be boosted up for bigger tanks. (No fear of flooding)
Float has to be Installed PERFECTLY Vertical. Mine got stuck on the first day. Luckily I was in front of the tank. I knocked the sensor and it stopped pumping.
No alarms. The motor will just pulse every 10 secs. You wont hear it unless the room is silent.
Does what its suppose to. If you're on a budget its a good buy. In hindsight wish I would have held out to buy the reg Osmolator with the alarms and laser eye!
Great Product By Justin on 3/24/2013

This is a great solution, especially for a nano reef. The magnet mounts are strong, and I am confident they will hold in place. The unit itself is tiny, and pretty inconspicuous, even if going into a display tank rather than a sump. The only drawback I see is it is a bit noisy when compared to my other tank, which I use an aqualifter on for the ATO.. but it is not obnoxiously loud.
1 bit of info that might be useful to include in the product description is the diameter of the pump. This could be important depending on the top off container that is used. For my purposes, I used a small potable water container designed for a boat or RV. The biggest opening was 1.75 inches, which I thought would be ok for the pump. Turns out the pump diameter is 1/8" larger, so I had to cut a new hole in the tank using a hole saw. No big deal, but would have been nice to know the size before ordering.
Perfect for smaller tanks By Ronald on 3/24/2013

Bought this top off for our 29g tank. Set up took about 5 minutes. Very easy. I really like the back up timer of not letting the pump run for more than 2 minutes. Really assures that im not going to over fill my tank.
