Algae Control

Expert Advice

Algae are microscopic aquatic plants constantly being introduced into the pool water by rain, wind, dust storms or other means. There are numerous varieties – some are free floating, some grow on walls and other surfaces. If not kept under control, algae can discolor your pool water, clog your filter, cause unpleasant odors and produce slimy, slippery walls and floor. Algae growth is common when the sanitizer level in the water is low or neglected. If the sanitizer is maintained at the proper level at all times, algae will never be able to grow.

Algaecides are used to prevent growth and treat existing algae that survive general sanitizer dosages. Robelle Algaecides provide an effective way to combat algae and prevent future algae from forming — keeping your pool healthy and clean for daily enjoyment.

Different Algae Types
Green		Green algae are the most common type found in swimming pools. Its severity can be as minor as a green tint in your pool water. It could be as harsh as dark green, fuzzy growths all over the pool’s surface and the color of the water so dark that you cannot see the bottom.
Yellow or Mustard		Yellow or mustard algae is common especially in the southern states. It is most often seen as patches of dark yellow dust which covers parts of your pool wall and floors. It usually starts in corners of the pool, near the steps, by the ladder, and other areas where the water circulation is not good. Unless algae gets into cracks, pits or crevices of the pool surface, mustard algae will brush off easily.
Black		Black algae are the most difficult type of algae to remove. Its severity can vary from as minor as a few small black spots to covering the entire pool surface. Black algae are difficult to kill because its roots grow deep into the pool surface and it has a tough outer coating.
Pink		Pink algae are frequently called “red algae”. It may be pinkish in color but is not an alga. It is actually a bacterium that originates from salt water. Polymer Algaecides are an effective treatment against bacterial problems.
