Filled in late summer 2018 with half "soft" and half hard water due to not understanding pool fill was not going through softener and also the softener regen process. CH is 800. Winter here in southern AZ so figured I'd do it in the cooler months. Waiting on answer from sewer folks about if they can forgive a month of the high water bill. They average Jan/Feb/March water bills to get your sewer bill. I'm going to double check the fill water chems before executing. Also planning on giving the tile a good scrubbing using the tile walkthroughs on this site. Anything else gotcha wise so i don't waste 11,000 gallons of water?
