algae control with high stabilizer

[thespian49]

Thank you, this may help. What do I do with the 'distilled water'? Do I add bleach to the skimmer or directly in to the pool water?
my readings this morning :
TH 200, FC 3/4, PH 7.5, TA 180, CYA 100.

The distilled water is just for testing pH, when the chlorine is high, and CYA when the CYA level is > 100 ppm.

If your pump is running AND there are NO chemicals in the skimmer, you can add bleach directly to the skimmer.
