Total Hardness

Total Hardness

 

Total hardness is the total amount of dissolved minerals that have built up in your pool water. The total hardness of your water increases every day. This is primarily due to evaporation, which removes only distilled water and leaves the minerals behind. Each time that fill water is added to the pool, more minerals are also added. Over time the pool builds up too many minerals. (Usually after 3 to 5 years)

The desert southwest experiences some of the hardest water conditions in the country. Out of the tap the water is already “hard” meaning it contains high levels of minerals. Combine that with some of the highest evaporation rates in the country (1/4″ per day in the summer); this climate creates a hardness problem very quickly in swimming pools.

Below is a list of issues resulting from High Hardness in a swimming pool:
– Staining on pool surface and tile
– Poor water chemistry. (Often leads to poor water clarity, algae, etc.)
– Clogged filter elements (Causes high pressure on filtration system)
– Rough plaster/pool surface
– Increased swimmer skin and eye irritation

To reduce hardness and to help prevent the issues listed above, it is necessary to drain and refill your swimming pool periodically; every 3-5 years. If you are unsure whether or not you need to drain your pool the best thing to do is have a hardness test preformed on the swimming pool water. 250 ppm – 500 ppm is considered normal. Above 500 ppm is high.

Green Algae

Green Algae
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:

    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:

    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)

Important Pool Water Maintenance Tips Every Pool Owner Needs To Know

Important Pool Water Maintenance Tips Every Pool Owner Needs To Know

If you have a pool and want to make sure you keep it sparkling all year long, then you must devise a regular pool water maintenance routine. One of the main problems with swimming pools is algae can develop, and when this happens your water will become contaminated beyond the point of which you can safely swim in it. This article will tell you about what good pool maintenance is all about.

pH Range

The pH level of your pool basically refers to how acidic the water is. A pool with a high pH (acidic) is very likely to become filled with algae. Your target pH readings are between 7.2 and 7.6 (the higher the number, the more alkaline your water…low number is acid, high number is alkaline). If you can keep your readings in this range, you will be able to keep your pool water maintenance in check and not have to worry about growing algae.

If your pool water has a high pH level (above 7.8), then your water is too alkaline and you should add some muriatic acid or sodium bisulfate. Sodium bisulfate is used more often because it’s much easier to handle and there are no problems storing it. Whereas, muriatic acid comes in a liquid form.

Chlorine Level

For ideal pool water maintenance with no algae, you will have to maintain proper chlorine levels. Chlorine is responsible for killing any algae that begins to grow in your pool. If you have enough chlorine, algae won’t grow. However, you should know that chlorine is very toxic. It is recommended to keep your chlorine level at 1 to 3 parts per million.

Algaecides

If you administer any form of an algaecide regularly, then you help to ensure the algae in your water will never start to multiply. For instance, one chemical that interferes with the algae’s ability to complete the process of photosynthesis is called potassium tetraborate, which basically starves it before it can multiply. You can thus use this as a great pool water maintenance solution.

Brushing And Patching

Another pool water maintenance task is to clean the lining of your pool regularly, as this also helps to keep algae away. If your pool is lined with concrete, you can use a steel brush to brush it, but if you have nylon liners, you must use a soft scrub brush. By doing so, you will manage to dislodge any algae colonies that might have formed. Eventually they will be drawn into the pool filter system and filtered out of the water. Proper pool water maintenance will keep your pool sparkling all year long.
