Black Algae

[wallyc]

I have spent over $200 in treatments on the infestation of black algae in my pool. I have spent countless hours using pumice stone to break the heads of the deposits and then treated them with what was recommened by the pool company. What should I do now? I have a power washer and and tempted to drain my pool and blast the stuff off. I then wil probably use an acid bath to kill any thing left in the crevices. I don't know what the mixture of acid and water is for the acid bath. Can anyone help? Thank you for any help.
