Hi there!

Any Hydor ATO user out there, please tell me your experiences with this system. I'm looking to invest some money in a good ATO for my tank. Also, any other suggestion are welcome.

Thank you,

Carlos García
 
I've had my Hydor ATO running for about three months now. It works as advertised. The only issue I have is when I turn off my return pump (for feedings and water changes), the water level rises in my sump and sets off the overflow alarm, so I turn it off. I then have to wait about an hour after turning the pump back on before I can turn the ATO back on because the electronic overflow sensor has to dry out.
