Maintenance

Circulation

Caring for your pool is more than just adding maintenance products. You must know some basic information about the circulation and filtration system and their roles in pool care before sanitation can be discussed.

The Role of the Pump

The heart of the circulation system is the pump. It moves water from the pool and sends it through the filter for removal of any dust, dirt, and debris prior to sending it back to the pool.

The primary question that most pool owners have is, “How long should I run my pump?”

There are too many variables for one universal answer. Piping size, pool size, swimmer load and the actual pump size all play a role in determining how long you should run your pump. For the proper “run time” consult your professional pool builder. They can determine, based upon all the variables, the proper amount of time required to keep your pool clear and clean.

Remember - if your pump is not running, the water from your pool is not being properly circulated or filtered. Running the pump and circulating the water is the best way to help prevent problems.

What is Filtration?

The Filtration System

The job of the filtration system is to remove any undissolved dirt and debris from the pool water. While the skimmer basket and the hair and lint basket in the pump all play a role in the filtering of the pool water, the primary element of the system is the filter itself. Consult your pool professional in understanding the role that the skimmer and pump basket play in keeping your pool clean. Always consult your owner’s manual for specifics related to the type of filter you have.

Filter Types

There are three types of filters that are used in swimming pools to remove dirt and debris that enter the water through swimmers and the environment.

  1. Sand
  2. Cartridge
  3. Diatomaceous Earth (DE)

If you don’t know your filter type, your pool professional or pool builder can assist you in determining which filter you have.

Testing Your Pool

Testing your pool 2-3 times a week is important to maintain adequate water balance and sanitizer levels plus to insure swimmer comfort. Test strips are a quick (30 second) way to test the pool for adequate sanitizer levels as well as pH and total alkalinity. Proper testing also ensures that calcium levels are maintained and that there are no metals present in the pool water. These tests can be completed by you or your pool professional. In order to prevent scaling or corrosive action and to achieve maximum swimmer comfort, the pool water should be balanced to the following levels:

Test Range
pH 7.2-7.6
Total Alkalinity 120-150 ppm
Calcium Hardness 200-250 ppm (Concrete Pools)
Calcium Hardness 175-225 ppm (Vinyl Pools)
Free Bromine 3-5 ppm
Metals: Copper 0 ppm
Metals: Iron 0 ppm

Balancing pH

pH is the measure of acid and base in the pool water. The pH of the pool should be tested and adjusted, if necessary, on a weekly basis. If the pH of the pool water drifts to the acid side of the scale, corrosion of pool surfaces and equipment can occur. If the pH of the pool water drifts to the base side - scaling, deposits, and cloudy water can occur. Use a pH increaser to increase the pH of the pool. To lower the pH of the pool, use a pH decreaser. Follow the label directions for the proper amount of the products to add based upon test results and pool size. Take a sample of water to your pool professional dealer every 2-3 weeks for complete test and analysis.

NOTE: Always follow label directions when adding any pool maintenance products to the pool. Never mix products together. If unsure how products are to be used, contact your local pool professional.

Calcium Hardness

Calcium Hardness is the amount of dissolved calcium in the pool water. Low calcium hardness levels can cause plaster finish etching and shorten the life of vinyl liners. High calcium levels can result in calcium deposits on the pool surfaces as well as equipment. The proper range for calcium hardness in pool water is 200- 250 ppm (parts per million) for concrete pools and 175-225 ppm for vinyl pools. Your local pool profesional can test for calcium hardness on a regular basis when you take a sample of your pool water in for analysis. To increase calcium hardness, use a calcium increaser Follow the label directions for dosage rates based upon pool volume and test results. If calcium hardness levels are high, the pool should be treated to prevent any deposits or scaling on the pool surface or equipment along with preventing metal stains. If the calcium levels are exceedingly high, (in excess of 450 ppm) partial drainage of the pool may be required. Your pool professional can advise you of the best method for treating your pool if you encounter high calcium hardness. If tests indicate that you have extremely high calcium levels in your pool, take a sample of your fill water (water used to fill the pool) to your pool professional for analysis as well.

Total Alkalinity

To prevent the pH from “drifting” or “bouncing” up and down, the proper amount of acid buffers, or total alkalinity, must be maintained in the pool. The pool should be tested weekly with a total alkalinity of 120-150 ppm (parts per million) maintained. Low total alkalinity can not only result in pH bounce and fluctuations, but corrosiveness and the possibility of staining increase. High total alkalinity also can cause the pH to fluctuate as well as cause cloudy pools along with possible scaling. To lower total alkalinity, follow the directions from your pool professional. To raise total alkalinity, an alkalinity booster is recommended.

Metals

There should not be any metals present in your swimming pool water. Metals can cause staining in the pool and cause the pool to turn colors. The most common types of metals that appear in pool water are copper, iron, and manganese. Your pool professional can test your pool water for the presence of any type of metals. If tests indicate that metals are present in the pool, a stain and scale remover should be used on a regular basis to prevent staining. You should determine the source of the metals and remove if possible.

Sanitize with Chlorine

Stabilized chlorine products sanitize your pool water and kill bacteria. Stabilized chlorine products are protected from sun light degradation and are an ideal means to keep your pool clear and clean. Most stabilized chlorine products are available in a variety of forms:

Your pool professional can determine the best form and type of sanitization program for your particular needs. A free chlorine level of 1-3 ppm should be maintained in the pool at all times.

Sanitize with Bromine

You may want to use bromine instead of chlorine to sanitize your pool. Bromine tablets provide a reliable method for killing bacteria and keeping your pool clear and clean. To utilize bromine effectively, an automatic brominator should be installed in your pool. Check with your pool professional for the complete bromine story to see if it fits your needs.

Shock

Shocking the pool on a regular basis is an important element in keeping the pool clear and clean. Swimmers and the environment add waste to the pool that must be eliminated on a regular basis in order to prevent problems such as algae and cloudy water. Your local pool store offers a variety of products to shock your pool. They can recommend the product best suited for your shocking needs.

Algaecide

Preventing algae is the key to an enjoyable pool. Algaecides act as a backup to your normal sanitization program and prevent algae from starting and growing in the pool.

Algaecide should be added after every shock treatment. Your pool professional has an algaecide for every need and budget.
