New liner put in an approx 10,000 gallon pool with main drain this spring, has a Haywood sand filter and pump. It has always seemed cloudy, last couple weeks has turned green. Pool supply place said to keep adding liquid cholorine (added approx 20 gal so far over the past couple weeks). Also added soultion 60 Algaeside and muritic acid. Realize algae can grow in filters and ladder...we backwash the filter, sweep the pool...just the other day added 3 gal of liquid cholorine and the next day test kit indicated no cholorine in water. Does anyone have any suggestions?
