This is about 3 years old, used it with my first Solana tank and has not been used in about a year. It is the old style without the new magnets, but works the same and is easy to install. There are some clamps, but I just silconed the track to the inside of my sump wall and it worked great.

These have dual sensor, an optical that is very sensitive and then a backup float sensor. The pump supplies the water to the tank and the controller regulates the level. Only used with RO water (no kalk), so pump is in great shape.

Comes with all the instructions and all the parts show below.

$135 shipped lower 48.
