FANTASTIC AUTO TOP OFF SYSTEM
After 7 YEARS of manually topping off the evaporative loss in my 150 gallon salt water reef tank I purchased the Smart ATO Micro. Can't believe I waited so long to add it to my system. Took me less than 5 minutes to set it up using a spare covered aquarium as my reservoir. The system works flawlessly and my water level has never been so stable. In my opinion a much better and more reliable option than any of the float valve systems. I am so surprised at the quality and completeness of this system and would recommend it very highly, just don't wait 7 years.
This thing is perfect. I was using a regular dosing pump with a timer set off for it to run for so many minutes per day and it would never keep the level right. It would either be too high or too low. Easy to set up and works flawlessly to keep the water level exactly where I want it. Don't listen to anyone who says you can't put it on painted or opaque surfaces. You absolutely can. The magnets are strong enough unless you have some thick 12+mm glass. I also don't understand why they say it's only for smaller aquariums. It seems to me it would work on any size. I'm using it on a 75G with 30G sump.
