Help - Black Algae in the Pool? What Next
I live in Houston, TX and have a grey plaster pool with moss rock/flagstone coping. Over the past several months, I have developed a pretty bad black algae problem.
The black algae is present in over 300+ spots (about the 1/4 dime size) and along the sides of the flagstone tile.
I have gone to several pool stores and have gotten many different treatment plans including copper, trichlor and other chemical treatments. I really don't know who to believe.
My water is relatively clear and my chemicals are is good balance (free chlorine, cynauric acid, Ph, etc.) I don;t think I have been running the filter long enough.
I realize black algae is very strong and requires a lot of scrubbing to pentrate the organism. Can a pool expert please recommend an effective treatment plan including the chemical(s) that work best?
Thanks in advance for your help.
