Just put in new liner so total refill(26,000 gal) added bleach until it was in range next I added 4 CHLOR-GUARD pucks (1 per 5000 gal) still some of 1 left. I know I need to add more plus we just had so much rain my pool overflowed and then I had to pump some water out but did the test for CYA anyway. The water didn't cloud up at all,I'm using the taylor with 3rd season regents(always kept in basement). What do you think bad regents/not enough pucks to show CYA yet or both? Thanks
