17600 gallon pool
I used the pool calculator to determine the shock level for mustard algae that was floating in the pool this morning with these readings.
CYA 80 (we don't have a SWG and the pool is in full sun all day)
TA 300 (He wiped the tip of the bottle with a damp cloth inbetween drops)
I had him put in 5 bottles of 96oz. bleach according to the pool calculator.
After 1 1/2hrs I had him retest. It read:
pH 7.5 (the water returns are pointed to the surface of the pool still)
TA (he stopped at 22 drops because the green was turning blue instead of red. He said he kept putting in more drops but it kept getting bluer)
So, please tell me what am I doing wrong?
My pool is still green and we can see maybe the 3rd step down and there are only 4 steps leading into the pool. After reading Pool School I've been going round and round. I don't understand because I read this site last year and had the pool all clear.
Thanks for any and all help!!!
