Looks like a good setup. A couple of comments I have... You'll need a circulation pump and a heater in the salt-water make-up tank to mix the RODI water with the salt and heat it to the desired temperature.
If you want to go to the nth degree, you could have another hopper with salt mix with a load cell on the make-up tank. You could automate adding the salt mix, the water and the mixing. Unfortunately, Apex controllers don't take generic 4-20 mA analog signal inputs or outputs. For this sort of thing you'd have to buy a separate PLC (programmable logic controller).
I was thinking of automating this water change. But as others have mentioned, I use water change time to clean the DT of hair algae, cyano and detretius. Except for scraping algae, this is the only thing I don't have automated in my tank (Auto-feeders, ATOF, Ca Reactor, Light timers, etc.. make life easier).
