- diaphragm pump
- auto top
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+
High quality product, worth every cent.
It was very easy to install
