Good when it works By Sally on 8/9/2019Sally wouldn't recommend this product to a friendI've had this ATO for over a year on my 80 gallon. It's great when it works, but several times it has woken me up at 2am or worse, come home from a trip and it's beeping because it's offline. I contacted tech support about the issue, they told me to "clean the eye." I've been keep reef tanks for over six years, that was not the advice I was needing or expecting. All the while right next to this ATO is my 40 gallon using a IM Hydrofill. I've had that for over four years, not an issue. Time for a switch and more peace of mind.
Great product. By KT on 7/3/2019KT would recommend this product to a friendWorks perfect and as described. I had it for over 4 months now.
Works well for me By TimS on 6/30/2019TimS would recommend this product to a friendI installed one of these on a 27 cube and it has worked flawlessly for about a month now. If you have a rimmed tank, you might have to make some mods to accommodate hose holder. I modified an old Tunze holder. The magnet is strong enough to hold right through a plastic rim, so no problem there. You do need to make sure (per the instructions) that the siphon break does not slip below the water level in the reservoir, but that's not difficult.
Can’t buy replacement pump By Isaac on 6/9/2019Isaac wouldn't recommend this product to a friendI had this for 5 months until the pump broke and no longer works. I got online to see if I could just buy the pump but you have to get the whole setup again. I wouldn’t mind spending 50 bucks on pump once in while but that is not the case.
Not Reliable By Brad on 5/24/2019Brad wouldn't recommend this product to a friendThis device consistently over Fills. I adjusted the electronic eye so it is not overflowing the tank but when it overfills past the sensor the unit beeps which is very annoying.
Reliable By Chad on 5/9/2019Chad would recommend this product to a friendThe price is right and EASY!! 5 months of use!
Awesome product By Billy Pipes on 3/15/2019Billy Pipes would recommend this product to a friendBeen running this for about 3 months. So far I love it!!!
Great product, reliable so far By Allen on 3/8/2019Allen would recommend this product to a friendI've had this for a couple of months now and so far it's been very reliable and has kept my salinity level extremely stable. The pump fits easily through the mouth of the standard white jugs many of us use for water changes.
