Turning Your Green Swamp Back Into a Sparkling Oasis . It takes a LOT of chlorine. Get a good test kit and keep adding chlorine until you start to get a Free Chlorine (FC) measurement then keep the FC at 40% of the Cyanuric Acid (CYA) level until the pool is clear. Keep the pump running, brush, and clean the filter if the pressure rises.
