Water-Specific Issues

Algae blooms when chemical levels are not in the recommended ranges, routine maintenance is ignored or not performed regularly, circulation is poor or non-existent, and filtration is ineffective. Basic pool care is mandatory to keep algae from growing in your pool water and spreading quickly, making it more difficult and more expensive to deal with.
Several things could be the cause. First, check to make sure that the pH is within proper range. If the pH is within range, it could be that you have a dirty filter and it needs to be cleaned. If you have a sand filter, this doesn’t necessarily mean to replace the sand, but to use a filter cleaner, such as GLB FILTER CLEANSE, that will remove both organic materials and minerals.

Check to make sure the sanitizer in the pool is in proper range. If it is not, raise the level. Another cause could be the amount of calcium in the water. If too much calcium is present, it can become cloudy. Adding a sequestering agent, such as GLB SEQUA-SOL, on a weekly basis, can prevent this.

Lastly, particles too small to be easily filtered out could be causing the cloudiness. A clarifier, such as GLB CLEAR BLUE, can be used in order to make these particles filterable.

Metal stains can be caused by any number of metals being introduced into the pool. Most commonly they appear as dark brown or rust colored stains on the walls, bottom, and plastics in the pool. Once stains have developed, removal involves diagnosing the stain to determine which metal (iron, copper, or manganese) is causing the stain, balancing the pool, and removing the stain using the appropriate stain removal chemical. Once removed, it is essential to clean your filters after 24 hours to remove the metals from the pool. Ask the water analysis experts at your local Hawaiian Pools for more information on stain removal.
Pool water composition always includes some undesirable elements that actually contaminate the water and reduce the efficiency of the disinfectant or sanitizer. Material such as hair spray, suntan oil, cosmetics, perspiration and other organic material react to combine with the chlorine in the water to form “combined chlorine”. Once “combined chlorine” forms, it acts as a very poor disinfectant, contributing to eye and skin irritations and the forming of unpleasant chlorine odor. Pools with this problem are often inaccurately accused of having too much chlorine.

Routine shock treatment is necessary to destroy combined chlorine compounds and restore the chlorine sanitizer to “free chlorine” efficiency. A pool can be shock treated by adding large doses of chlorine, commonly referred to as superchlorination, or by adding a non-chlorine shock such as GLB OXY-BRITE.

Constant sanitation is a necessity of maintaining a clear pool. Through the use of chlorine tablets, salt chlorination, or biguanides, sanitized water kills germs and bacteria and prevents the growth of algae when combined with the 5 key basics to pool care.
No, this is not true. Salt chlorinating systems turn salt into chlorine through electrolysis. This is the only chemical that salt systems produce. It is still <strong>mandatory</strong> that all other chemicals be balanced on a weekly basis.
First, you must add the algaecide according to the directions. If you don’t add the correct dosage amount, it won’t kill any of the algae. However, be aware that using the entire bottle of algaecide is also ineffective. Not only will you spend additional money, large doses can also lead to staining and foaming in your pool.

In addition to properly dosing your water, it is also recommended that the algaecide be added in the morning on a bright sunny day for best results. Algae are plants and grow in the presence of sunlight. Adding algaecide during algae’s best growth time will increase intake of the algaecide and make it more effective. If black algae is present, brushing the algae at least once daily will also help expedite algae removal. Brushing the dead cells away makes the living algae more vulnerable to the algaecide.

No, you don’t have enough “free chlorine” in your pool. Most pools contain both good chlorine and bad chlorine. The good chlorine is called free chlorine and is capable of killing germs. Bad chlorine, on the other hand, is called “combined chlorine” and is a poor germ killer.

Too much combined chlorine in your pool causes the strong chlorine odor. When the combined chlorine level reaches 0.2 ppm or more, it is time to shock your water. Shocking will eliminate the odor.

Equipment-Specific Issues

Filtration is the mechanical system for removing visible matter from the water. The filter medium is designed to remove hair, dirt, minute skin flakes, metal or calcium precipitates and other visible debris that would otherwise cause the water to be hazy and cloudy.
At a minimum, you should run your pump 12 hours a day. Running your pump 24 hours a day will provide the best clarity.
Approximately six to eight years normally if the pool water is well maintained and balanced regularly.
If the pool is well maintained, a new plaster should last about eight to ten years. Keeping your pool water balanced helps prevent normal wear and tear of the plaster.
Pump motors typically last 2 to 5 years. Filters will usually last 6 to 10 years (sand in sand filters should be changed every 2 to 3 years). Automatic pool cleaners such as Polaris’ and Legends last roughly 3 to 5 years. Timers and other mechanical equipment usually lasts 3 to 5 years.
