I started to see these black dots on the bottom of my pool. I thought they were the diamond brite stones. After taking my brush to them I realized they were small black dots or pockets (capsules) of algae. I try to keep my FC as low as possible in my pool. I am aware of the CYA / FC charts or ratios.
If I brush the pool, breaking the algae pockets, raise my FC slightly higher, and use PolyQuat 60 at the maintenance dose, can I stop this algae from spreading. I do not want to shock the pool. I have a long awaited week off and it starts on Friday.
Mind you the black dots are few and far between. Maybe a 100 or so. Besides the few black dots the water clarity is 100%
Thanks in advance.
