I don't know if this is algae or not; hoping someone could help. I have vacuumed the pool every other day for the past week and the following keeps showing up on the bottom of the pool in the same spots.
I have put in algaecide; and kept my chlorine level up to 10ppm for the last 10 days. my total alkalinity is 120, and ph is 6.2, stabilizer is 35.
Any help with this would be greatly appreciated
