My source water (city water) has a CH of 175, and although I don't add water every week, I do add it about every 3rd week, about 1500-2000 gallons. My CH is running high, 875-900, so I find myself adding acid every other day to keep pH and TA lower(CSI is rarely in a good place). Since my pool is covered and gets no rain water, should I get a water softener to remove the calcium from the water that I add to the pool? I am worried about getting scale on my heater and SWG. Thanks.
