There are more than 65,000 species of algae known to humankind. Approximately 50 of these may be found in your pool water.
While pool algae can never be totally eliminated, it can be controlled. Common pool algae vary from the ‘mustard’ green/yellow type that exists in suspension, to the green clinging, ‘black spot’, which is actually dark green/black.
The latter builds a protective barrier of impervious wax around itself and is particularly difficult to remove when it colonises. Algae may develop in crevices or corners where circulation is poor, but will be highly unlikely to form if chlorine residual has been maintained at all times and circulation is adequate.
For this purpose, an automatic pool cleaner and an automatic chlorinator are excellent combatants to algae. Pool cleaners also help to prevent algae growing by physically preventing it from clinging to pool walls. In dry conditions the algae plant dries up into spores and is carried by the wind. Once a spore finds favourable conditions for growth, it flourishes and regenerates every 20 minutes. Chlorine is the most effective algaecide, as it will prevent algae from forming if you maintain correct sanitiser levels.
