Pool algae problems are by far the most talked about complaint of many swimming pool owners and operators. Algae is plural and they are one-celled green looking marine plants that grow in pools and spas. There are several thousand species of algae that can and will populate your pool or spa.
However, the most encountered algae found in swimming pools/spas, is the green algae type.
Green algae are by far the easiest of all pool algae to treat. You can get rid of green algae quicker than yellow algae (also known as mustard) or the dreaded black algae.
Swimming pool algae are said to bloom considerably when they come into contact with water that offers the right conditions for their growth.
One thing to always remember here is this...algae will only develop or start growing in a poorly chlorinated pool or spa. This is why you must always maintain your pool chlorine between 2 and 3 ppm.
Chlorine is just one of the pool chemicals that must be constantly maintained for you to control any potential pool algae problems.
Now, you may be wondering if having algae in your pool or spa is dangerous! On the contrary! In fact, there are many health tablets and diet supplements that have algae as one of their main ingredients. However, under the right conditions...pool algae growth can become dangerous.
This usually happens when the algae convert the natural sunlight into food; thus, releasing its waste products into the water of your swimming pool. This process will develop or cause your pool water to become the right environment, which will be the ultimate feeding ground for many harmful bacteria and other micro-organisms.
As I said before, you will not have pool algae problems if your pool or spa is properly chlorinated. But in a swimming pool or spa that is poorly chlorinated, algae can reproduce at an alarming rate.
Because of this ability, algae can turn your clear looking swimming pool into a green algae producing pond. This is one swimming pool water problem that can happen overnight. For the trained eye, you can usually tell when your pool chlorine level is not right. This is usually noticeable by the hint of green and dull looking appearance of your pool water.
The level or type of pool algae problems that you may encounter often depends on the color of your pool water. In fact, swimming pool algae are mostly grouped by their color. These tenacious little green marine plant colonies, need and love environmental conditions such as sunlight and temperature to bloom.
You will have pool algae problems in areas of your swimming pool or spa where there are:
These diverse types of pool algae problems fall under several groups as previously mentioned. These groups include:
Every swimming pool/spa operator and owner has at some point, or another battle some pool algae problems in their facilities. Algae spores constantly enter our pools and spas by several means. These include the wind, the rain, your pool equipment, and in some cases contaminated swimsuits.
Fortunately for us, (apart from the dreaded black algae) algae cannot develop in a pool or spa where there is an adequate amount of pool chlorine present.
This would be your effective amount of residual or free chlorine. Don't get me wrong, algae can live in your chlorinated pool water, but it cannot develop there.
Whenever you notice the green or black intruder in your swimming pool, it simply means that your chlorine level was at some point zero. In the case of black algae, your chlorine levels could have been at zero for two or three days.
With everything else, prevention is always better than cure. As a pool/spa operator or owner, we don't have any control over the environmental factors that contribute to the growth of algae in swimming pools. You can however, control some of the nutrients that do contribute to pool algae problems.
One way to do this is to ask your swimmers to shower before entering the pool or spa. Other preventive methods that you can take include:
Other useful ways that you can prevent pool algae problems or algae growth, are by super chlorination and the use of a pool algaecide. You also must ensure that your pool or spa is thoroughly cleaned.
This means that the surfaces of your swimming pool walls must be brushed, and the pool vacuumed regularly.
Always keep in mind that...it is easier to prevent pool algae problems by preventing pool algae growth.
Once you allow algae to bloom in your swimming pool, getting rid of it can become a little tiresome.
However, if you want to get rid of your pool algae problems, then, you must take certain steps to do so.
To get your swimming pool or spa looking bright and sparkly again, you must destroy the algae completely and correct your water chemistry at the same time. Some of the more common methods or steps you can take to correct this pool water problem are:
Now you know the truth about the appearance of algae growth in swimming pools and spas. Now you can take the necessary steps to eliminate and prevent your pool from turning green due to certain pool algae problems.
