I was really freaked out about my high chlorine levels until finding this site! My pool is 18 ft in diameter and 4 ft deep - Vinyl.
I have a FC of 10 and my CYA is 135.My ph is high ( 8 ) and after reading a bit on this site I am assuming I need to lower the ph, but that FC is fine due to elevated CYA. .... Yes??? The TA is 150.
Up until about a week ago I was using chlorine tabs in one of those floating chlorine dispensers. I removed them last week due to the FC levels I have.
Again .. to make sure I am understanding .... with CYA levels high I do not want to continue using the chlorine tabs but instead use bleach. Is this correct?
How do I know how much bleach to add to maintain chlorine levels for optimum sanitation?
