Was at the pool place a few weeks ago picking up some filter cleaner. While I was there a guy I recognized from work was getting some algaecide. He had an algae bloom. On the way out I told him he didn't need it and he should just come here and look up BBB. I bet him lunch he could clear his pool up in a few days. He paid up today. He said his family loves how clean the pool is and he now spends more time swimming and less maintaining.
