Well I can't wait on the CYA as I already put it in. My chlorine levels held for over 24hrs. How long should I keep it high 15ppm. Or should I say how long until the dreaded black algae is dead. I figure once I get it squared away I'll let my chlorine generator keep it in check. I'll definitely check out the BBB page. Thanks for your replies. I'll post in a week or so.
