Algae

Problem
Algae in a pool may cause cloudy water, slippery pool surfaces on steps and ladders, pH rise, filter blockage and excessive chemical consumption. Algae can occur due to poor circulation, poor filtration, improper chemical maintenance, or poor housekeeping and environment. Algae do not cause disease, but their presence is not inviting to swimmers.

• Green algae - Tend to be free floating, making the water cloudy.
• Mustard algae - Cling to walls, leaving the water clear unless they are physically disturbed. When brushed, mustard algae appears to be a fine brown powder.
• Black algae - Clings to walls and are very difficult to brush.

Solution

• Adjust pH into the range of 7.2 - 7.4 with HTH® pH Minus or HTH® pH Plus at least one hour before shocking
• Shock treat your pool with an HTH shock product
• Brush walls vigorously using the HTH 18" Curved Wall Brush
• Run filter for 24-hours or until water clears
• Vacuum
• Add an HTH algaecide

Preventative Maintenance

• Maintain pH in the 7.2 - 7.8 range
• Shock treat your pool weekly
• Use an HTH® Algaecide regularly to prevent algae
