I started using the dichlor shock last night. My pH has remained at approximately 7.8-7.9 for the 2 weeks I've using only liquid bleach, but I noticed it finally dropped to 7.5 today. I know that dichlor has some stablizer in it, so that should begin to increase my CYA level shouldn't it? If so, how long do you think it should take to raise my CYA level high enough to show on a test?
