Not if it is going to re-crystallize, just enough water to fully dissolve the salt .

The saturation point is about 25%, and if you maintain temperature it should not precipitate. So volume vise you should be able to mix 7.5 gallons of water with 2.5 gallons of salt at room temp. Higher temperatures will allow for higher saturation.

This is all very cool!

Does anyone have any pictures or sketches?

where do you get these valves or solenoids from?

I am going to post what I imagine but don't know where to get the parts from...

Where is the salt coming from? so far I see drain then water topped off with fresh water, I'm assuming that's what you mean by the auto top off.
