Pool is 2 years old, CYA is 100 plus, FC is .5 but my pool has a bunch of supplemental sanitizing junk per what I have read here but has been sparkling, crystal clear. See signature for specifics. Fired the pool guy who just dropped in 3 Chlorine pucks per week and chargeed 200 per month thus the high cya. My wife is having a big event here and I want to shock the pool the week before the event to be sure of no issues (she is not happy I 86'd the pool guy). I have been doing water change-outs using the spa water every other day but the cya is still over 100. I am using Bleach too and no pucks to keep from increasing CYA. What do you think I should try to get my FC too (low end) for shock level? I have 5 cases of Clorox on hand now.
Thanks....
BTW- DALLAS TX is the location.
