  • Perfect..!! By Dinoflagellates on 4/23/2015

    I should bought this ATO a year ago an forget the daily top of. This set is all I needed for my 150 gal reef aquarium..!
  • Worth the price By Andrew on 4/19/2015

    I got this ATO unit to replace an old JBJ unit I had on my 55 gallon. What a step up in quality. I really like the 2 sensors; the laser sensor to measure and monitor water level for the ATO and the float level for backup to prevent overfilling. Works like a champ! This unit has its own water pump which is a big plus. Made by Tunze in Germany. Build quality and engineering of a BMW.
  • Would recommend this product to a friend By James on 4/12/2015

    I liked this ATO so well I bought a second one for a tank I have set up in another part of the house. Its simple to use and maintain. The instructions are almost too detailed, in my opinion, I had to read them several times but they are effective. I like the two different means of shut off, the electronic sensor and the float valve. BRS TV should consider a video installing one of these and setting up the electronic eye, to support the complicated instructions. Great product IME.
  • Best ato By Mike on 3/29/2015

    I pick this unit up two years ago on Black Friday and it's been running like a champ since. as the BRS YouTube video indicates the laser as well as the mechanical part of this provides a great backup is fairly easy to put together which sometimes is in the case with Tunze Products but this is been doing the job for two years.
  • Works perfectly By Chris on 3/27/2015

    I love this thing. It works perfectly and has never failed. Not much else to say than that.
  • eliminated manual topoff By Greg on 3/23/2015

    I like it So far no issues. The reviews were good. Instead or trying something I am usually using others experiences to save me the anguish of poor decisions
  • A necessity By JonnyReefer on 3/19/2015

    It's so nice not having to get 3 half-gallon cups per day and bend down to refill my sump. And no more micro-bubbles! Although the little nut&bolt that holds the output line to the tank attachment was a PITA to get on, it was a breeze to set up.
