The Tunze Osmolator is the ONLY top off unit that is allowed on my systems. It has an optic sensor and a float sensor back up with alarm. I have 3 of them that I have had for years, and none have failed me yet. Replacement pumps are stocked at J&L Aquatics (and other places too I'm sure) too, so if there is pump failure a quick and easy fix is just a couple days away (J&L has quick shipping).
