Killing Green Algae
Green algae are the type of algae you see in the water itself. The water itself has a green color to it. If your water is turning cloudy, chances are you are about to have green algae in your pool. If you have cloudy water, shock your pool with chlorine at the rate of one gallon or one pound granular chlorine per 10,000 gallons of pool water and run the pool pump for up to 24 hours. If the pool has already turned green an algaecide will be needed in addition to the same shock treatment mentioned above. Simply add the chlorine as mentioned and immediately add one quart of “algaecide 60” per 20,000 gallons of pool water. Run the pump for 24 hours and re-test the chlorine level. Add more chlorine and run the pump longer if needed. Make sure the filter pressure stays within range. If the starting clean pressure of your filter is 10 lbs. then you should clean the filter when it goes up 8-10 lbs. above that. So clean this filter when it hits 18-20 lbs. Brushing the pool may be needed if you notice algae forming on the walls and floor of the pool. Algae that form to the walls grow a protective layer that makes it difficult to kill without brushing it away from the wall. The algaecide used for green algae is “algaecide 60”.
