Keep going! Mine did that too! Keep brushing and keep at it. The milky water pic shows that you indeed were actively killing the algae. That is exactly what you want to see. Your CC level and the yellow cloud show it's not done yet though.

One of the local pool stores told me to use a nylon brush as a metal brush would be to hard on a plaster pool! I can't tell you how PO I am right now. So.... I guess that could contribute to my algae issues. I will get a metal brush and clean my pool! Any suggestions on what I should be using for a plaster pool built in 78, with some etching??
