I'm not good at Chemistry so can use a bit of help. I have been using the Bleach part of the BBB method so far. Here are my test results:
Last year my CYA was way high and I had to completely drain the pool. My understanding is that CYA can only go up but I am seeing it going down. It was about 40 last month. What could be the reason? I don't want to add too much stabilizer and drain the pool again. The Pool Calculator suggests the following:
Increasing TA: Add 94 Oz by weight/75 Oz by volume Baking Soda,
Increasing CH: Add 118 Oz by weight/95 Oz by volume Calcium Chloride (don't know what that would be in BBB terms),
Increasing CYA: Add 53 Oz by weight/56Oz by volume or 138 Oz liquid Stabilizer.
Just want to confirm from experienced people if this is what I should be doing?
