I have a reef type tank in the basement as my sump. I got a KENT marine shut off float and installed it with the float in the overflow chamber so it doesn't get buffeted by my powerheads in the tank. (My overflow stays full because I drilled hoes in the bottom) I put a TEE in the product water line from my RO/DI unit. One tube goes to a 50 gallon trash can also equiped with a shut off float, the other to the float in my sump. When the water level in the sump drops, fresh water bleeds in from the RO unit. Since the evaportated water is constantly replaced my salinity stays vary stable. Great when I am out of town.
This could easily be modified to a sump that does not have an overflow by attaching the float to a piece of plexiglass and clamping it to the side of the sump.
