Swimming Pool Algae

Swimming pool algae blooms happen. Most often when the free chlorine falls below the required minimum level to prevent algae growth or the free chlorine is marginal with poor circulation.

CONTROL THE PHOSPHATES that enter the pool thru rain water run-off of garden and lawn fertilizers. These Phosphates feed the algae and may cause an algae problem despite adequate chlorine. One day, you notice the pool water appears cloudy and off to work you go. You return home to a green pea soup.

Don't panic! Go out and get 6 gallons of 12% liquid shock. Pour it in and try to raise the free chlorine to about 30ppm.

The algae will clog the filter so backwash as often as needed until the bloom is controlled. Could be every 4 hours.

You will notice a great improvement, if not clear water within 3 days.

For maximum chlorine efficiency, maintain pH as close to 7.2 as possible without going lower.

In high phosphate conditions, using a phosphate control will allow efficient sanitizer performance.
