Here are my AM numbers after 2 days of round the clock filtering and lots of 6% bleach.
I know I don't want CYA high - had that issue last year but am thinking I need to raise it some to have bleach work. I have a small bottle of stabilized chlorinator for my spa that is 100% sodium dichloro s-triazinetrione dihydrate. Can I use that to raise CYA a bit and how much do I use for 30k gallon pool?
Also, even though chlorine degrades during the day in sunlight, I keep adding it every hour to keep at shock levels until the water clears - is that correct?
Thanks for the help guys - love this forum.
