Its types and appearance
- Green Algae are very tiny plants that grow in untreated water. Once present in water they may be recognized initially, by the formation of slime on the sides and floor of the pool developing into a general cloudiness in the body of the water. In the advanced stages of growth, they take on a green color and, if allowed to progress further, will take on a brownish color. Intense sunlight is very conducive to algae growth by causing increased water temperatures and more rapid loss of residual chlorine. The following three forms of algae are most commonly found throughout the Southwest Region:
- Green algae is the most common form of algae. It appears as a streaky, slimy buildup, first noticeable on steps, in corners, and on the plastic surfaces of skimmers and return fittings.
Yellow or Mustard Algae:
- Yellow algae, also known as mustard algae, usually starts on the shady side of the swimming pool. Yellow algae has the same slimy texture as green algae, but it is more difficult to remove. Yellow algae thrives in shade, and will often appear in covered pools. This form of algae grows in a long, streaky pattern, appearing on pool walls, in corners, and on steps and love seats.
- Black algae is the least common form of algae, but once it blooms it is the most stubborn and is the most difficult of the three to eradicate. Black algae is a water borne spore, and is carried into your pool through the fresh water used to fill your swimming pool. Black algae is usually the result of insufficient chlorine levels for an extended period of time. Black algae is most often found in leaky swimming pools that require near-daily replenishment of pool water. As large amounts of water are added to the pool, chlorine and stabilizer levels drop, promoting an inviting environment for black algae to form its roots.
- Should algae be allowed to gain a foothold in the pool, “shock” treatment is often necessary to remove the growth.
- It is commonly known that black algae is so stubborn and resistant and in many cases deeply embedded into the plaster and can only be controlled and not completely eliminated. An Acid Wash and Chlorine bath does not always work; sometimes re-plastering the surface is required to completely eliminate black algae. In most cases, i clean Pool water treatment system can control and many times eliminate visual black algae from your pool. (If anyone can do it our professional chemical service can)
