  • Worth Every Penny! By Chris on 11/19/2015

    Easy to set up and install. Totally worth not having to add water to my tank everyday. All i have to do is keep an eye on my ATO reservoir and refill it once a week. Definitely one of the smartest purchases i have made for my reef tank!
  • Love the system, Pump is a bit noisy By Nicole on 11/12/2015

    Just put this in my FW tank since the boyfriend hates the sound of running water and I hate hauling buckets every couple weeks to prevent that noise. Awesome that I can connect a separate pump instead of the original if I feel like it ( I won't, too broke now). I plan on getting another for my future saltwater tank.
  • Sweet By Kurtis on 11/9/2015

    This top off is awesome to say the least, very easy set up and works great. Alarms great feature and the control unit is user friendly. Only issue is the system is on the pricy side, but very happy with it. Everybody needs one.
  • Love By JOE on 11/9/2015

    I've had this pump for maybe close to a year on my 150 gallon and i couldn't be happier the the setup is easy and i have never had one issue with this thing love it compared to my jbj ato on my 90g.
  • 1.5 years of operation, still like its out of the box!! By Devin on 11/6/2015

    This ATO is amazing! it functions so well, and is so user friendly! over 1.5 years of operation and ZERO issues!!! I do replace the pump every 8-12 months just in case, but have yet had one fail on me!
  • Awesome Product By Martin on 11/6/2015

    Worth every penny. Excellent quality and performance. Simple to install and very adaptable.
  • Works ok By Steve on 11/2/2015

    I've had this running for about week now and for whatever reason it is filling up too high at times and setting off the alarm. The small pump is also incredibly loud. It's irritating when it's turning on every 10 minutes. I expected better all around performance for a ATO at this price range.
  • Excellent product! By Tony on 10/30/2015

    You can't go wrong with this ATO!
  • Love It By David on 10/30/2015

    This is truly one of the best top offs i have seen the piece of mind is all i care about love the fact it has 2 ways it monitors. Love the fact it has a alarm when it goes to high and shuts its self off, a bit pricey. You get what you pay for, i had another one that the switch would get stuck and start running and running until pulled it down. This is a must buy if you want piece of mind when your not around
  • Piece of mind, stable salinity By Adam on 9/15/2015

    Wow, what a great purchase. This is the way to keep your tank topped off for evaporation loss and keep salinity EXTREMELY stable. Drop dead simple with two forms of measuring water needed. Takes about 5 minutes to install and get running. This is especially helpful when I travel and have a sitter care for the tank. All they have to do for water is keep the top off jug full and everything else from a water level perspective is covered. I really love this product. This is the best solution for automated top off I have seen.
