My pool is just over a year old and has always had a high acid demand, adding acid every other day would keep my pH balanced. I recently installed a SWG (IC40) and now I have to add acid everyday. I bring the pH level down to 7.2 and 36 hours later my pH will be 8.0+ (off the scale). Here are my readings, is there anything I can do to slow down the pH rising so fast?
