auto top off ideas

[schmidt01]

How do I add an auto top off to my sump? The sump is in the basement, so space is noy much of an issue.

I have a 60 gallon tub being fed with my RO unit. RO unit has a float switch shutoff.

Tunze Osmosulator then pumps directly from the 60 gallon tub into the sump. The osmosulator sensors (float and infared) are mounted in my third chamber of my sump where the return pump is.
