So I have a Taylor test kit and I also take my water for testing at our local pool store. I have my chlorinator set at 75% and at times turn on my super chlorinator because we have very little FC. I notice on my tanning ledge and steps that I have the little black spots of algae. They are not big and the don't cover the whole surface. So I do but some algaecide in and extra chlorine tabs. Anyone have suggestions to help? My pool gets tons of sun all day long.
