  1. Please don’t waste your $100

    This product gave me the quality I would expect of an ATO i bought at a crappy fish store for $25. This thing is junk, it’s so loud, and the float valve is the only sensor, so if it fails, (and it will) then you tank will either be dumped to overflowing with RO water or your tank will be saltier than the great salt lake. Float valve gets stuck nearly every time i try to use this product, plastic is trash quality. I would love to refund it but I hadn’t even used until months after I bought it.

    I've had this for at least 2 years. The system works great as long as you clean the float switch regularly and don't let it empty the RODI container.

  4. Failed in 4 months

    Bought this for my lagoon 25 at first it was great then at the 3month mark it started just not topping off every now and again. I cleaned the pump and sensor with citric acid and it was working again or so I thought. Now it only pumps immediately after plugging it in, so I replaced the pump, added cardboard to the magnet on the back of the glass and still it wont pump unless it is unplugged and plugged back in again. Do not buy this.

    I've had the 3155 for years and it is great. I thought this would have the same quality and reliability as 3155 for a nano tank. It dose NOT.

  7. Junk

    Failed twice within the first 2 weeks of install. I should have taken all of the terrible reviews into consideration. It drained my reservoir dry even though the float was literally underwater. Terrible engineering.

    This is my second one. I don’t know why I spent so much money on this junk. Should have 1 star across the board. Failed twice in the first month, both in the on position. Overflowed the DT, thank goodness it was only 1/2 gallon. Unfortunately it was in my 13.5gal so adding 1/2 a gallon of rodi water was no bueno. Wish I could return it.

    As previously alluded to in an earlier review of mine, this product is not safe. Failed within a few days of install in the on position. Loud. Very poor quality. Really disappointed in this product and especially at its price point. BRS please pull this from your site.
