Digital timing won't work for me. My rate of evaporation changes lots, especially seasonally.
I like the looks of the JBJ unit. I'll have to figure out somehow to mount it in my reservoir. You can set a sensor in your reservoir so the unit doesn't run your top-off pump dry, but the bracket looks like it could only place the sensor about 6" down. I want a deeper reservoir than that.
Those brakets are for the fish tank sensor, not the holding tank.
I used a 37g plastic garbage can (marked FISH ONLY) for my holding tank. I had the utility pump on the bottom of the can, it was plugged into the JBJ unit and a hose running to the tank/sump. Then I took the second sensor and zip tied it to the top of the pump...so if the water ever goes that low, it will stop pumping water just before the pump is exposed to air. The other sensor was placed into the fish tank (or sump) at the desired water level.
If any of you can find a replacement sensor...PLEASE let me know.
