Revenge of algae in your pool

We are also at higher risk this time of the year due to algae. Environmental conditions such as light and temperature are important to support algae growth.
Algae contributes to increased risk in several ways. First, it is a slip and fall hazard. In addition, algae may harbour bacteria, increasing the risk of Recreational Water Illness (RWI).
Algae can also increase the risk of drowning for the following reasons:
l Algae on the pool bottom, especially at transition points from deep to shallow water, may challenge weak or distressed swimmers. 
l Algae can cause water to be cloudy, increasing risk of collisions, injuries, and hiding swimmers in distress.
It is very important that algae is controlled to minimise the risk of illness or injury.
Keeping water free of algae is more important than merely maintaining sparkling clear water.  Information on algae prevention and other important maintenance topics can be found via your local pool company.
Preventing and eliminating algae
Algae are single-celled plants that present a major concern for pool owners and operators. Though algae is aesthetically unattractive, it also increases slips and falls and cloudy water hazards.
The pool operator has little or no control over the environmental factors that influence the growth of algae.
Sunlight, outside temperature, and humidity are facts of nature.  Algae spores are carried by the wind and there are thousands of species of algae that can contaminate and grow in a pool.
Algae may even be present in the source water used for fill purposes. Some algae species have the ability to reproduce rapidly, turning a clear pool to green in less than a day.
Algae are most commonly grouped by colour into three groups: green, black and yellow (sometimes called mustard).
Green algae is by far the most common and the most easily controlled. Black algae is usually found growing on pool walls in areas of poor circulation, such as the deep corners of the pool. Yellow algae, which is sometimes difficult to control, often require treatment with a specifically formulated algaecide.
The nutrients can be controlled to some degree by insisting that users shower before entering the pool, especially for the removal of suntan lotions.
The risk of having an algae bloom is reduced dramatically if the disinfectant and pH are maintained at proper levels.
Operating factors such as proper filtration, circulation flow, and elimination of dead spots can help prevent algae. Also, routine super chlorination and use of an algaecide are useful tools in the prevention of algae growth.
An algaecide is a good second level of protection if the disinfectant ever gets low. Brushing the pool/spa walls on a routine basis is an important preventative measure as well.
Once algae start to grow, they will rapidly consume the chlorine, promoting further algae growth (blooming). Therefore, prevention is the key.
Fortunately, there are many effective algae prevention products and algaecides to kill algae once it starts growing. Your local pool chemical store or service company can help you select the correct chemicals for your pool.
When selecting an algaecide be aware that some algaecides cause foaming. If you have an attached hot tub that agitates and aerates the water, foaming can become worse.
Now that water temperatures are warm and kids are getting some early summer swimming, remember to keep diligent and brush up on the fundamentals. Keep the water chemistry good and prevent algae growth with proper disinfection, water balance control, and preventative measures.
Enjoy your summer!
