Test as of 30 minutes ago:
(25Gal in ground pool, vinyl)
TA 60 (it was 70 last year)
CYA 20 (it was 60-70 last year)
I have small amount of algae present (of course at this FC level I would) Lots of rain lately. My pool is full sun all day. (when it's not raining
It's not holding chlorine. I have not shocked, but added 2-4 gal of 8.75% bleach every other day and still have low FC.
This is my second season with BBB . I have lower TA levels and lower CYA levels than all of last year. I would like to know if I have to also address these other levels. They seem on the low end of acceptable but are different than all of last summer when my pool was perfect.
I know I have to shock to get rid of the algae, but should I raise the CYA and TA before shocking?
Thanks for any help
