  • Easy and high quality By Chris on 6/6/13

    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 6/4/13

    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 5/24/13

    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.

  • Budget Friendly By Victor D on 4/30/13

    Pros
    Compact
    Magnet attachment
    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)

    Cons
    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 3/24/13

    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 3/24/13

    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.

  • does and donts By daniel on 3/11/13
    daniel would recommend this product to a friend
    ok i got this ato for to do 2 things add kalk and add top off water at same time. i put it on my redsea max 250 that i upgraded with a refugium because the filter and skimmer just dont cut it on this tank so i built a custom sump for it. after i put the tunze top off in the sump i set it up where when it tops off water right where it poors over the last chamber witch caused current to let me know it was keeping it at same lvl. if theres a little water current it will kok the float bobber some what and wont let it drop freely so make sure if you get this to make sure it tops off enough to make less water current are add something to keep current away from float bobber. other then that i found no issues so far with this product plus it has a run time that if it runs to long it wont run no more and wont until you unplug it and back in to reset it. plus the little pump that comes with it works awsome cant complain.
