My pool has algae. I need a few tips.
Saturday evening, I added enough bleach to bring Chlorine to around 15 - 20 ppm. CYA was 50. No help.
Sunday morning, I added 5 lbs. 73% Cal Hypo. Pool is around 20,000 gal. No help.
This morning, I see some dead algae has fallen to the floor. Pool is still very green, though.
I don't have a test kit to measure above 5 ppm. This is labor day, and so I need to do it by guess-work.
What I am wondering is how much Cal Hpo should I add and how long should it take before you see a change in the appearance of the water? Should I just add a pound every hour until water color starts changing?
I have never had to do this before.
