TA and CYA Concerns

[saint_malachy]

I have a 15' AGP. My results as of this morning are as follows:

FC - 5
TC - 5
CC - 0
pH - 7.5
TA - 120
CYA - 25

How concerned should I be about the high alkalinity? My water is sparkling clear and I have very little pH fluctuation. Also, is my CYA too low? Although I've switched to bleach, I have eight left over 3" tablets. How much can I expect my CYA to rise if I use these? Thanks for your help.

Eight trichlor tablets would raise CYA by between 40 and 55. That is approximate because 3" trichlor tablets can be 7 or 8 oz, and the pool volume will vary a little depending on water depth.

I would use three of the tablets now (one at a time) and then switch to bleach.
