I did the 20 ppm about a week ago from sunset to sundown but for sure lost more than 1 ppm so what does that mean? I have been able to hold a FC reading above 5 ppm the last week but until yesterday had been losing 2-3 ppm . Im away again so had my brother in law check pool the night before and it was at 3 ppm so he added like 5 quarts of bleach at sunset and let pump on. Last night was still 7 ppm so will check tonight. question with much time away am I overall better looking at SWG or do all teh same issue stay the same with checking daily etc? Thanks
