Green Pool – Algae

Green Pool – Algae

Algae are widely regarded as a pest organism in swimming pools and enter the pool from rain, wind and dust. Although not directly harmful to people, dead algae cells do provide food which can sustain more harmful organisms. Algal photosynthesis also causes chlorine in your pool to be consumed more rapidly, reducing the chlorine available in your pool to kill other harmful organisms. Long filtration times are required to remove algae from the pool water and the algal cells are often the main component of the rubbish which blocks filters, requiring them to be backwashed more frequently. Even small amounts of algae can make a pool look cloudy and unclean.

Some types of algae exist suspended in your pool water, however most algae form green-black spots on the walls and floor of the pool. The latter type builds a protective barrier of impervious wax around itself. Chlorine is prevented from entering into the barrier and therefore cannot kill the algal colonies. One of the active ingredients of algaecide will break down this protective coating, allowing chlorine and the other ingredients to kill the algae. Treatment of very bad cases of pool algae involves the owner scrubbing the top layers of dead algae off alga clumps; therefore exposing the algae, which can then be affected by the algaecide and chlorine.

It is important to note that algae in highly unlikely to form if the free chlorine residual has been maintained at a satisfactory level at all times and the circulation is adequate.

We have available a pool algae eliminator.

There are two ways of eliminating algae from your pool – prevention and cure. All current treatment aimed at eliminating algae use some kind of poison e.g… chlorine or algaecides. The better way to ensure your pool is algae-free is to starve it of the nutrient which is what causes it growth – phosphate. Growing algae feed on the phosphate in pool water and dead algae release phosphate back into the water. By removing the phosphate from your water with a phosphate remover, existing algae will be starved of food. Spores entering a pool which has no phosphate will not flourish.
