- diaphragm pump
- auto top
This is by far the best ATO currently out there. And I have tried a LOT of them. You will not be disappointed.
I have not set up my new ATO yet but the customer service was great and the item arrived quickly.
The auto top off works great. I've had a few float switchs stick and cause floods. i think this air switch design is a great improvement. the diaphram pump is the best i ever used. A lot more lift and pressure than the aqua lifter i've used before.
My second avast ato and hands down they are the best. This time it was for a qt tank and I bought the wall plug version. A+
