Been trying for weeks to shock. Thought I was done yesterday CC.5 now back up. Pool is blue but still cloudy. Testing with the TF-100. Had to keep shock way up thought CYA was 60 from pool place but appears to be higher now when I test if I've done it correctly? Used calcium chloride from pool store to raise CH now out the roof. Just using Chlorine to shock and doing the BBB now. Back washing, vacuuming and using new clean machine. Is it cloudy because of high CH? What should I do at this point I have shocked and shocked used 40+ bleach. Please help I've read pool school but still feel like I'm doing something wrong. Should I drain some water at this point to get rid of CYA and CH? How much would I need to drain? Below the skimmer? Thanks for any help I'm so tired of trying running out of test material for some of the tests because of high FC to shock.
