My cya level is getting pretty high from using pucks for the last 5+ years right now its about 70-80 what is a good number to hold the cya at? my pool is 38,000 gallon with a sand filter. I live in indiana & the pool does have an auto cover on it. I was going to start draining & refilling this weekend to get the cya down & i have quit using pucks. im currently in the middle of a slam. just wanting to know what a good cya number is?
whats a good cya level to shoot for?

Me, too. Why use so much bleach clearing water that will just end up on the ground or down the sewer?
yes i realize that now! ( could have saved alot of bleach money) is it ok to do some partial drains while slamming or should I wait till the slam is done?
ok I will do some draining when i get home, about how much water will I have to change to drop it from 70 to 40 in a 38,000 gallon pool any idea?
Not quite half.
You will probably need to do it in incriments to keep from damaging your liner. Always keep at least a foot of water in the shallow end.

I wouldn't try to get CYA all the way down to 40 right now. CYA at 70 can be managed if you have to, though somewhere between 50 and 60 would be better. CYA will tend to drop over time if you stop using products which are constantly adding more. You can target 40 longer term.
