I just opened up my pool. It is a green algae cesspool.
So I have started to SLAM (as best I can, EDIT: What I mean by that is that I can keep shock levels but I do have to go to work so occasionally it will dip down to below shock and then I will keep it shocked all through the night and most of the day - this weekend I will continue to keep it shocked continuously).
My last reading (TF-100) was:
CYA = 35
FC = 16, CC = 0
ph = 7.2
I noticed because I have to backwash my DE filter a lot, my CYA is gradually going lower (it was 40 which is why I wanted FC to hit 16).
Question, how low can CYA go before I need to restore it? How do you normally restore CYA?
I do have a few Pool Logic TriChlor tablets I could throw into the skimmer which I assume would slowly raise my CYA count.
EDIT: Wait a minute, you can buy stabilizer. That was a dumb question. Sorry. And it looks like 20 ppm is the lower threshold based on the pool school chart. Man, I am having an off day.
Anyway, the pool HAS been getting back to blue after 3 straight days of SLAM (it's green again because I wiped the floor a little to break up the green algae bloom).
