I've got an RO/DI with an automatic shutoff valve, but this only cuts the supply when the output has been restricted. I'll be dumping the RO/DI into a freshwater reservoir from which I'll be feeding my tank via a LiterMeter and Nilsen reactor.
My only problem now is finding the best setup to control the level in the freshwater reservior. I know I'll need a solenoid of some sort to control the RO/DI output line. Any good solenoid recommendations for a 1/4" RO output line?
I'll also need something to turn the solenoid on and off.
I've heard a simple float switch isn't recommended in this application because it won't run the RO/DI system for a long enough period of time to get the best water.
I'd like to run one of those relay systems that rely on 2 float switches, but I don't think anybody makes one of those (and I've got too many other things to do so DIY is out for now). The relay system I'm talking about is one where the circuit is closed when the lower float "trips" and remains closed until the upper relay trips. This way the RO/DI can run for longer periods each time it comes on (and presumably get better quality water out of the RO, using less DI, etc.). Can a ReefFanatic level controller be configured to work like this?
I've also thought about using the Spectrapure "single tank liquid replenisher" - but it doesn't use a relay system (it uses a air pressure float switch). Anybody use one of these?
Any other thoughts or suggestions?
