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

I would like to start of buy saying I have been in the aquarium hobbies for over a decade and had always taken steps to reduce evaporation as much as reasonably possible. However after many years of topping off my tanks manually I decided to look in to an ATO, after reading many reviews and seeing a few videos I settled on this one and I'm glad I did. The ATO is very simple to to set up in just a few minutes. The sensor that goes inside of your aquarium is very small and the magnet used to secure it in place feels adequately strong enough that I'm not worried about it falling inside of my aquarium. I purchased a smallish 7 gallon water container one would use for camping to use as a reservoir for hold additional water and the small pump head fits very nicely inside. So far it has been working great. There is very and I mean very little noise heard from the pump when it kicks into action and the only time I've heard it was when everything in the room is shut off and its stone silent in the room. The only draw back that I can think that may throw some people off is the sensor it's self is a very very bright night light so best not to use in a bedroom I'd say if you like the dark that is but seeing as the aquariums in question are located in my home office / game room it doesn't bother my in the least. I have plugged my ATO into a smart plug to make water changes and gravel vacuuming easier as I can disable it while doing so. Hopefully people find this review helpful. 😊

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'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 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.

Had an issue with my particular item, but the seller reached out and made everything right. Would recommend. This item is such a time saver and keeps my tank looking great

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 heard about these cheaper ATO’s overflowing their tank. This one works great and the good news is you will never have this issue if you just turn it on the 1-2 mins/day. It quickly finds the height of the water and kicks on/ into standby accordingly. I have this installed into a 5gal bucket with holes for the check valve and power cord. It lasts me for weeks with a 55g reef tank with lids on. And with a check valve the pump doesn’t get taxed much and should last for a while. The box did arrive wet/ and slightly damaged, but the product was fine. The device’s magnet is strong and holds through about a 1/4” with a very strong grip. The pictures are accurate. Device is about the width of a nickel’s diameter.

I have been running this product on my 5 gallon tank for about 4 years and it runs great. I just ordered another one for my 40gallon tank, and the product stopped working after a month. the light burned out, there is no indicator light. not sure if this was just a bad batch. 5 stars for my first purchase, 2 stars for this purchase.
