Filtration of your pool is extremely important.  Pool Manufacturers recommend 8 to 10 hours of continuous filtration daily. The total gallonage of your pool must be pumped through the filter three times per day to be effective.  This also assumes that your filters are clean and in good working order.


This condition is a result of insufficient filtration or an indication of a problem with your filtration system.  Clean your filters and make sure that they are in good working order.  Cloudy water can also occur when pool covers are left on for extended periods of time.


If you use a pool cover, you should expose the surface of your pool water to the air 50% of the time.  Pool chemicals will not react normally if not exposed to the air.  Please be sure your pool cover is off on your service day.  If you install a safety cover, please provide operating instructions for the service person.


When your solar system is in operation, the flow of water through your filter can be reduced by 50% or more,  You should increase your filtration accordingly.


Our service together with your brushing and proper filtration will eliminate all forms of algae.  Some strains of algae such as Black Algae are more resistant and will take more time to die and disappear.
