Green Pools and How to Treat Them

In many cases your pool may go green due to various factors.

At Pool and Spa Mart Bull Creek we can help you with treating your green pool either by yourself bringing in a water sample to the Store, so that, we can analyse your water sample with our computerised testing equipment.  We will provide you with the solutions and advise on how to bring your green pool back to a sparkling and swimmable condition.

Or alternatively, you can organise for one of our experienced service technicians to come to your home and do all the work for you and conduct a green pool treatment.

Why does a swimming pool go green?

A swimming pool can or may go green due to lack of sanitiser, filtration/circulation issues, not running your pool equipment long enough, incorrect chemical balance and organic matter entering or being left in the pool for too long.

What is the green in my pool?

The green in a swimming pool is actually algae.

Algae spores enter a pool constantly.  This can be due to wind, rain, and decomposing leaf matter left in the pool, warmer temperatures, presence of nitrates and phosphates.  These are some of the few factors which will promote algae growth

Algae, is a living organism which can multiply rapidly if not treated.

What problems can algae cause?

Firstly, it is unsafe and not recommended to swim in a pool with algae, as algae contain toxins that can be harmful to bathers.

Algae can also cause staining on the surface of the pool, clog the filter and cause filtration issues.

If the Algae is not treated correctly you will have constant issues with keeping sufficient sanitisation levels in the pool. It is best to use the correct algaecide and companion chemicals to ensure that you eradicate the algae.  If not, you will have reoccurring algae problems.

How is Algae prevented?

Proper chemical balance and sanitiser levels are crucial in preventing algae from growing in your pool.

General cleanliness of the pool is also important. Regular brushing of the walls and floors to prevent dirt harbouring spores to become food for algae.  Any organic material and bacteria will contribute to algae growth.  Therefore, regularly emptying the skimmer box and pump baskets of debris, scooping and vacuuming the pool of debris on a regular basis is essential, sanitiser levels to kept at the appropriate levels all year round and good filtration/circulation is essential.

What other Types of Algae is there?

Besides green algae there are several other types of algae which can affect your pool.  They are:

  • Mustard Algae – which typically starts by clinging to the walls of the pool, it will then spread to the floor.  Mustard Algae, is a chlorine resistant algae which often looks like dirt or brownish-mustard colour sand on the floor or walls of the pool.  It has organisms within it which acts as a defence mechanism against the workings/oxidation properties of sanitisers (ie – chlorine).  You will note with Mustard Algae that you can brush it away from the surface/s of the pool, however it will return quickly if not treated appropriately.
  • Black Algae – commonly grows in cracks and pitted areas of the surface of the pool (predominately in concrete/plastered pools). As Black Algae, does not look green, please do not think that Black Algae is not a living or growing organism because it is.  Black Algae has a protective layer on the outside/top layer of the algae.  This layer enables the Black Algae to be resistant to normal chlorine levels and therefore, more difficult to treat and keep at bay.
  • Pink Algae –  is a form of bacteria which can appear in spots/of a slime consistency which appear in parts of the pool where there is no direct sunlight and has limited water movement.  A common place is behind the swimming pool light lens.  Yet again like all algae’s pink algae occurs when your sanitisation levels are low and lack of filtration/circulation of the pool water.
