The problem with algae
How to prevent this blooming problem in your pool!
Did you know there are over 20,000 known species of algae? And they just love sunlight. So that means pool owners really need to keep on top of algae in order to maintain a sparkling clean pool.
Algae are a group of non-flowering plants, which appear in the pool as green, brown, yellow or black slime often resembling fur. It thrives in corners and steps where water circulation might not be as thorough as elsewhere in the pool.
When you brush algae from the pool surfaces, some will immediately flake off while a fair bit remains stubbornly attached to the plaster, appearing as a stain. It is fairly easy to brush algae from smooth surfaces, such as fibreglass, but very difficult to brush it off rough plaster where is can burrow in the cracks and crevices.
Unfortunately, algae can have an impact on the water chemistry components themselves. For example, algae can break down bicarbonates in water, raising the pH significantly and adding alkalinity at the same time.
So what types of algae are there?
How is algae prevented?
Proper chemical balance and sanitiser residuals will prevent many opportunities for algae to bloom. High pH and low chlorine (or other sanitiser) can give algae a great start to genesis. General cleanliness of the pool is also important. Regular brushing of seemingly clean pools prevents dirt from harbouring in the pores of the plaster, which is a good start for an algae colony.
The use of algaecides is recommended to provide a back up to normal sanitation and filtration processes and is completely necessary for many pools. Swimart stocks a range of algaecides from Aqua-Health and can give you information on which products will suit your pool and how they are to be used.
