I'm 99 % certain that the algae is gone. Nothing dead in the pool, nothing coming out of the back wash. I still have a cloudy pool
Here are my latest numbers:

water temp 70
FC 6
TC 5
CC 1

Ph 7

ALK 80

Cal Hardness 50

CYA 50

I know I have to get my Ph up, and my Calcium Hardness, but which do I take care of first? Is it going to be harmful to my pool if I don't get my hardness up? I have an 18 x 33 AG with sand filter.
Thanks,
Marlene
