Auto Top Off for Saltwater Aquarium Water ATO System for Both Reef and Fresh Tank - Blue

Working great so far. Been using this to pump water from our main tank filter to another smaller tank. Havn't had any issues yet, I'll be sure to update if needed. Nice to take advantage of our main system. I might cover the light with a sharpy later. No leaking yet.

I bought this before I went on a cruise. I didn’t want my dog sitter to have to mess with refilling our 10 gallon salt water tank. This has been so convenient for us even after the cruise! It’s very quiet as it refills.

I've now purchased 3 times. All 3 of these are absolutely garbage. They work for ruffly 1 to 6 months and then ultimately fail.Reviews say it's great, but notice none of the reviews mention "Years of use".Longevity wise, this gets 1 out of 10. Waste of money.The pump is a 2 out of 10. It's slow, small and breaks easily. It's the kind of pump you'd expect to pay about $1 for.The sensors are NOT water proof and in fact the sensors will take in water and then create a film inside that destroys the sensor.All in all, this is an epic waste of money. Amazon should be ashamed to sell this product, as it's designed to break and you will need to replace it again and again and again.Quite frankly, I'd like my cash back. This is a scam product in which I have 3 of. 3 is enough to prove a point. If the seller or anyone at Amazon would care to interject, maybe we could establish some accountability. For this product, there is none.Buyer beware. This is a disposable product with a shirt lifespan. Absolutely rubbish.

I was a little leery of this thing at first given the previous one (different brand) that came with the tank I bought had stopped working… but so far, this thing is great. You just have to make sure to clean the sensor every week or so.

Fue fácil la instalación y funciona bien

had it running for a week. Keeps my salt filled perfect with ro water the only down I’ve noticed is snails can go on the sensor and make it start filling but it’s only happend once, it does flash to let you know it’s filling so it’s pretty noticeable

I purchased one of these last summer, For whatever reason, after about 6 month,s it stopped working.I messaged the seller, and within an hour, they responded and, without me asking, requested my address.They sent me a brand new ato unit, not just a pump. They were quick and responsive. These little pumps are going to fail over time. But I did not expect them to handle this swiftly, let alone at all. 5/5 customer service and support.

I don't want to completely diminish this product. It's not hard to assemble or use. It's small and indiscreet if you can cover the light of the sensor. For the price you pay it's decent.I do worry that the sensor maybe isn't as water proof as it needs to be. It will likely stop working before a year. I have purchased two. One is still going the other has a solid red light when powered on and in place and will no longer operate. I have tried using both distilled water and 99% alcohol to clean the sensor and it has not worked. I even soaked the sensor in alcohol overnight. The only other thing I can think to try is maybe cleaning the pump. I'm pretty certain it is finished though. If you can, try to place the unit and disturb it as little as possible. I think when I removed it recently and let it dry that was what ultimately did it in.Simple set up and mechanism. Decent price and design. Poor longevity.
