    Old main drain cover missing

    Green pool shocked -> recurring brown algae

    You guys seem very knowledgable and I was hoping you could help me with this one. Over 4th of July I was out of town and came home to a dark green pool. I shocked it twice and got rid of the cloudiness which took a week of running the pump constantly. Since then I have a recurring algae...
