Help...pool was overrun with some green algae this past week. I installed an inline chlorinator and was experimenting with the levels when the chlorine level dropped down to 1ppm. Not to mention the pool temp got up to high 80's. I shocked the pool overnight with DiChlor and got the levels up to 12 ppm. I have the pump running continuously and I brushed the walls. How long will this take to clear up? What else should I do?
