CYA Level Question

[elsie]

Ok, ok, I know we're in one of the hottest months of the year, but still, in a brief few weeks I will be covering up my IG pool for the season since by then, what with diminishing sunlight and cooler overnight temps, the water will be too cold for this fish.

I strictly use bleach. My CYA is between 30-35. Is that sufficient to hold the chlorine in for some 8 months when the pool is covered, or do I need to boost it up? It just happens that I'm going to be in the vicinity of the pool store this weekend which is 35 miles from home, but I don't want to spend $$ on another bottle of stabilizer if 30-35 CYA is sufficient for winter CL retention purposes.

Appreciate anyone's yeah or nay!

I don't believe any amount of CYA is sufficient for that unless your climate is very cold.

Last August my CYA was about 45 and it held the chlorine for the entire time, opened to 6 or 7 ppm...

I would leave the cya where it is

The way I look at it , the worst that could happen is you open to a green pool. I would rather deal with that, than dealing with a cya level you're not comfortable with .

Algea = easy to get rid of

cya = not easy to get rid of
