Very cool, I am surfing through everyones setup, and steering toward what you and @pelphrey have done. What is your display/sump volume?
I have a Red Sea Reefer 250 - 65 Gallons total water volume. I don't keep salt mixed up, just 80 gallons of RODI. 80 gallons will last me a minimum of 2 months, most of the time longer!
