When your pool has turned green, it is most likely caused by an insufficient amount of available free chlorine in the water. If left untreated, the algae will continue to bloom along the floor and walls of your pool. The quickest and easiest way to remove the algae bloom and return your pool back to normal healthy conditions is to apply a shock treatment that is specially conditioned to this specific problem. Adding a combination of chlorine and algaecide will destroy the organic material that causes the green contamination in your pool. Once the algae has been destroyed, we remove the contaminates through a simplified filtration process. The process can take anywhere between 3-7 days, depending on the severity of the problem. The longer you wait, the longer it will take to return your pool back to normal. Please call us immediately if you require assistance.
