For Sale Double Float ATO from autotopoff.com

40$
2 floats with the pvc guards

The reason it's 10$ below retail is because I added about 13 ft of premium wire between the sensors and the box/plugs.
Saw about 4 months use before I had to move and switched to a smaller tank. Been sitting in my closet for a bit

 

Still in my closet, if you don't have an ATO it's a pretty decent option that's nice and cheap! (willing to ship too)

 

Still available, not pretty but it works. Remember it has 12 ft or so between the control box and the floats, so depending upon setup, there's lots of cable.
