As the CH gets higher than that, CSI is tough to keep in range as you cannot manage your TA and pH low enough. First sign for me is the SWCG starts releasing calcium scale flakes into the pool. Also the water line tile scale buildup increases. Beyond that, you can get full on scale build up on your pool shell.

If your water use / cost is a big deal in your area, I suspect they have Reverse Osmosis services that come to the house and remove the TDS from the water. You sitll use about 25% new water volume.

I noticed Pure Water Industries that provides on site filtration is in my area. Do they charge by the gallon?
