I have a few comments/questions please.
Background:
I have used 3" slow tab chlorine in my pool for 30 years
Often at the end of the season, I have a green algae problem
This year the good folks on this forum have helped me identify what is probably going on.
Last (Sept 3, 2021) water test results from Pool store:
free chlorine = 22.54 ppm - (I had shocked it recently)
Total chlorine = 22.54 ppm
Combined chlorine = 0 ppm
pH = 7.2
Hardness = 203 ppm
Alkalinity = 100 ppm
Cyanuric Acid = 102 ppm - I believe this is a large part of my problem, way too high!!
My plan for next year's season is:
1) Stopping 3" tab and switching to liquid chlorine (non-stabilized)
2) Switching to Liquid shock (non-stabilized)
3) Getting the CYA to a better level
4) Testing the water myself and often (TF-100 kit)
Does this sound right?
- thanks, Ken
