  • Confused By on 7/21/2017

    I have replaced the power supply because it wasn't working. Once I did that, I noticed the pump wasn't working, so I replaced it. I still do not have the pump working, but the controller will indicate when the water is low, or too high, and will give a green light when it isOK. Any help will be greatly appreciated.

  • Got my $'s worth By on 4/5/2017

    I had this pump running off the osmator for eight years and it ran like a champ for that time frame topping off my tank with RO water. After pumping water 12 feet from my storage tank to the sump for those 8 years, it finally lost its mojo and I had to replace it. I hope to get another eight years out of my replacement Tunze pump.

    I was having Issues with the old pump. They new one works so well. I hope I get another 3 years from this one. :)
  • Works but you need to read the directions By on 2/25/2017

    This unit is designed for smaller tanks. It is designed to shutoff after a period of time regardless of the float to protect from over filling a small tank. That's why you had to unplug it and turn back on. There is a jumper to stop that. See manual. Ps it also will save your pump from dry running.
  • Excellent System By on 12/28/2016

    I have been running my TUNZE ATO system for about 4 years. I started out with a 50 Gal reef adn after two years upgraded to a 125 gal reef, and the TUNZE ATO has run through the transition flawlessly. I purchased a spare pump when I purchased the system 4 years ago, and it is still in the packaging unopened. My original pump is still in service. I did run into a small problem after two years of service, as I used kalk in my makeup water, and the pump stopped working. I simply placed in a distilled vinegar/RO water solution and let it stand for a few days, and then the pump started working again. Kalk will definitely reduce the life span of pump as it was not designed to pump a pastey Kalk solution. I upgraded to dosing 2 part and removed Kalk from my system altogether. If this unit is running strictly RO water it will last. for a long time.
  • Just in case!! By on 10/17/2016

    I'm replacing my three year old pump, it still works but it's starting to make alittle more noise so for $20 I'm changing it and keep the other for a spare, never a problem with this ato!!!
  • Quality at a great price. Always have a spare By on 9/14/2016

    The Tunze ATO is the best ATO on the market and it's always good to have a spare pump on hand, because for the price, you ant afford not to.
    All around quality and easy to swap out/install. Small, quiet pump but still really strong.
  • When you need to replace your Osmolator pump ... By on 4/25/2016

    This is a cheap, easy replacement.
  • Good experience despite what some other people have said. By on 3/16/2016

    I'm still on my first pump that came with my osmolator, and it's been running for almost a year sucking kalk probably everyday in pretty much the most extreme situation possible for an ATO pump. I will happily buy a replacement before it quits just to have it on hand.
  • Great product! By on 12/8/2015

    Bought ato on EBay, so when pump failed I was out of luck with tunze directly. Customer service at tunze was fantastic through reef2reef forum. I'm quite sure had I purchased new, he would have just sent me a new pump immediately.
    I love this ato and I am not sure how I lived without it for so many years.
