Numbers as of today.
Cl 16.4
Ph 7.5
Cya 75
How do I keep my clorine at that number to kill the algae? Besides doing the usual cleaning, brushing, and vacuuming. I have 2 tabs in the floater and have been checking the chemicals daily in the moring. Is there something else I need to add? Should I add more bleach? There was 1 small spot of green in pool yesterday and the sock on skimmer basket was slight green this morning.
