I have an osmolator on a 120 Gallon tank with about 30 Gallons in the sump. Granted system size does not absolutely determine evaporation rate but mine isn't running that often that it is limited to the rate of the pump and I would love to have a system that had this problem

Continuing with this derail ... FWIW, I am running an Osmolator on my 280g, and with 3x400w halides, 4x54w t5's and 2x24 t5's, there is a fair bit of evaporation happening.

But the Osmolator is defective, it doesn't shut off (it gets stuck on). In the meantime while I am dealing with Tunze service about this, I just plug it in for a few minutes twice a day and unplug it when the water level gets to the level it should be.

Point is, the supplied pump is not slower than the rate of evaporation.

One thing you can do however, is get a 12V relay from an electronics supply store, splice that into an extension cord, run it off the top up and then you can run a Maxijet (or a solenoid valve or whatever you want) instead of the suppliied DC pump. You can also buy such a relay from Tunze although I don't see it listed anywhere, but the DIY project would be pretty simple (and probably around $10-20 in cost).
