How to Deal with Swimming Pool Algae

Swimming pool algae is every pool owner’s worst nightmare. Once it strikes, there is little pleasure in getting the sparkle back in your swimming pool. For this reason it is essential to follow a regular pool maintenance program and to catch swimming pool algae before it catches you.

Algae is the most basic form of plant life, and algae spores are carried into swimming pool water by rain and wind. For this reason our pools are most vulnerable to the scourge of algae after heavy rain or stormy weather.

Since swimming pool algae spores are microscopic and very light green in color, chances are you won’t even notice them in the water at first. But if it’s been raining or there’s been a lot of wind, and you are aware that the water lacks sparkle and looks a bit murky, take action immediately. You should also clear any debris (leaves, sticks and so on) that has blown into the water before it sinks to the bottom of the pool and starts to rot, polluting the water, staining the pool shell and generally causing problems.

How swimming pool algae grows in the water

Once the algae spores are in your pool, the algae will start to establish itself taking root in the grouting between tiles or mosaics, around under-water light fittings, in the mouth of the skimmer, in the corners of built-in steps and on even marble-plastered walls.

As the swimming pool algae grows, it changes from pale green to yellow, and then to brown. Eventually, if left unchecked, it will become black and spotty.

How to get rid of swimming pool algae

The best way to get rid of algae is to treat the water with an algaecide. If the attack is bad then you should also shock-treat (or dose) the water with chlorine. If you are using a salt water chlorinator check the salt levels because heavy rain can dilute the salt level and if this isn’t rectified then the chlorinator be damaged.

Whatever type of pool sanitizing method you use, it is essential to circulate the water through the filter and to make sure that both the pH and total alkalinity levels are correctly balanced. You can raise the pH with soda ash, if the pool is plastered (both gunite and concrete pools would normally be plastered), and with sodium bicarbonate if you have a vinyl liner or the pool is made from fiberglass.

If you don’t the time or inclination to treat your pool once algae has taken root, then call in a specialist pool cleaning service. We can provide you with all the advice you need to control and eradicate swimming pool algae. You are welcome to call or email us today.
