It's my least favorite test. It seems to have a mind of its own. Regardless, last week when I opened I was at CYA 30. Today I was at 20. I did it twice to double check.
Full results
pH - 8
FC - 5
CC - 0
CH - 325
TA- 70
CYA - 20
72 degrees with solar cover on.
Crystal TFP clear.
Last summer I was at CYA 30 pretty much the whole time but I seem to have dropped.
My question: From reading previous threads about using trichlor pucks I believe if each 3" puck adds 3 ppm of CYA in a 10,000 gallon pool then I will need about 9-10 pucks for my 27000 gallon pool to increase 10 ppm CYA (getting me to 30). I have never used a puck in my pool before so I have no idea how long it would take to get 10 pucks dissolved. Is that stupid? Should I just break out the CYA and the sock? I have a huge thing of pucks (that I bought prior to TFP) and would like to use them up.
Thoughts? Maybe one a week for a few a months on top of a sock addition?
