OK, so my pool is clear, but my FC late last night was 11.0 and dropped to 6.0 by this morning. I have not been able to get my FC above 12.0, my shock level should be up to 16.0 according to the charts. I decided to check my CYA level again because I had put some in the pool before i started this slam process and before I was being advised by trouble free pool.com. Since I know the CYA can creep up for about a weeks time, I was curious to see if it had raised. Ironically, I found that my CYA level had dropped. Initially my reading was about 35 (I was told on this forum to round that up to 40). Now my black dot is not disappearing, it is cloudy looking but definitely can still see it with the test tube of water full.
My question is if this finding a significant? I guess I'm thinking if I am shocking at a CYA level that is not accurate?
Secondly, why can I not get my FC level up to 16? I am following the pool Calculator every time I add more bleach. I am checking about every three hours during the day.
Third, I was not expecting to add this much bleach. What does everyone do with all the empty bottles!? I went through about 14 bottles of 10 % yesterday. I am on day 4 of slamming.
