Factors Affecting Quality Of Pool Water

clock June 23, 2015 10:00 by author medallionpools |

Here is a list and short descriptions of factors that can affect the quality of your pool water. Please note that all of the information below is generic and will not apply exactly the same way to all pools. Be sure to discuss any questions or concerns with your local pool professional.

BATHING LOAD- The more people that use your pool, the more disinfectant that you will need to control Algae and to properly sanitize your pool.

SUNLIGHT- The warmer the weather, the faster you will lose the residual disinfectant needed in the pool to control bacteria. You can make the residual last longer by maintaining the proper stabilizer level.

WATER TEMPERATURE- most pool chemicals will not last as long in your pool as the water gets warmer. The acceleration is even greater when the water temperature gets above 85 degrees.

WIND & RAIN- When you experience periods of wind & rain, these conditions will carry dust, bacteria and even algae spores into your pool. These items will overwork your current chemicals reducing their ability to properly sanitize your pool.

PH- When the PH level of your water rises, the ability of your pool water to disinfect bacteria will decrease. You need to maintain the PH level in the 7.2-7.6 range.

TOTAL ALKALINITY- When Alkalinity level is below 80 PPM, this will affect the PH level and could cause staining in a plaster pool or result in possible algae growth. When the alkalinity level is too high, above 130 PPM, this could cause cloudy water and scaling.



Why Is My Chlorine Reading Always Low In My Pool

For those of you who occasionally have this problem, here are a few possible reasons. Please remember that this information is generic. Your pool may have different requirements. See your Medallion pool dealer if you have any questions.

The sun will cause Chlorine levels to quickly dissipate if you do not have the proper level of Stabilizer. The proper amount of Stabilizer in your pool water will extend the life of your Chlorine. Cyanuric Acid is the chemical used as a swimming pool stabilizer.

The proper range of Stabilizer using chlorine as the sanitizer, should be in a range of 30-60 PPM (parts per million). For the customers that use Granular Chlorine, that product has no stabilizer built into it. You need to use Cyanuric Acid on a regular basis to extend the life of your chlorine. If you add granular chlorine to your pool in the morning and get a chlorine reading, that reading could be zero in the afternoon due to low stabilizer level.

For customers that use Chlorine tablets, stabilizer is built into the tablet and Cyanuric Acid may not be needed as often. The problem is when a chlorine floater is used and 3” chlorine tablets are placed in the floater, the pool may not be getting enough chlorine or stabilizer because these tablets do not dissolve quickly enough. This will result in algae and almost a zero stabilizer reading.

Using an Automatic Chlorinator with the chlorine tablets inside, will give you a better choice of your pool receiving the proper chlorine level and the proper stabilizer level. It is very important to get your pool water checked on a regular basis for the proper reading of stabilizer.

If you are using a Chlorine Generator (Salt System) the stabilizer level is extremely important. Most Chlorine Generators produce Chlorine at a steady pace without the high and low level spikes you get when using granular. Without the proper Stabilizer level to protect this Chlorine from the sunlight you could be losing it nearly as fast as it is being produced.



Automatic Pool Vacuums – Suction Vs. Robotic

Now that you have made the decision to get a automatic pool cleaner, what unit do you purchase? This will depend on what type of pool you have. Cleaners are designed for above ground pools, inground pools with flat bottoms and hopper (part of pool is deeper). Make sure you purchase the correct unit for your pool.

The suction cleaner has sections of hose you attach together, fill it with water and then install into your skimmer. This type of unit will move around your pool cleaning the floor and (in many cases) the walls. After your pool has been cleaned, you will turn the pump off and backwash the filter to get the dirt and debris you vacuumed out of the filter. This will cause some loss of water in your pool.

The robotic cleaner will not have any hose to attach or the need to fill the hose with water. This unit you will place in your pool and what it picks up will go into the unit itself, usually stored in a mesh bag. When you are finished cleaning your pool, you will remove this unit and empty the container inside the unit of what you have cleaned. This unit will have neither water loss nor the need to backwash your filter.

Both types of units will do a very good job. Discuss the various units with your local pool dealer to learn about your options and what unit will be the best for you to use for your pool. Make sure your pool dealer knows if you have an above ground pool, an inground pool, a flat bottom, or deep end.



Swimming Pool Chemical Safety Tips

When using any chemical products always read the labels carefully and follow directions precisely. Chemicals protect you when they are used correctly in your pool or spa. Here are some generic safety precautions, but please always read and follow the label directions.

1. Use exact quantities specified, not more. Do not overdose.

2. Don’t mix chemicals together unless the directions say it is ok. Add products separately if instructions do not say ok to mix.

3. Don’t add water to chemicals. Add chemicals to water.

4. Handle all chemicals, liquid or dry, with care. Store products in a cool, dry, well- ventilated area.

5. Always keep chemical containers closed when not in use.

6. For products requiring measuring, use a clean, plastic scoop (or scoop provided in container). Do not interchange scoop or place wet scoop in any chemical containers.

7. A responsible person should handle pool chemicals. Keep out of reach of children.

 

8. Don’t inhale fumes or let chemicals come in contact with your eyes, nose, mouth or skin.

9. In case of contact or if chemical is swallowed, follow emergency advice on product label and call doctor or local poison control center.

10. Don’t allow chemicals to stand on grass or landscaping.

11. Don’t smoke around chemicals.

12. Many chemicals such as chlorine are corrosive and should not be stored near metal products like bicycles, lawn mowers, cars, etc.



Why Does My Swimming Pool Get Cloudy

clock June 9, 2015 09:48 by author medallionpools |

Many factors go into answering this question. Some possible reasons are;

1. Dirty filter or baskets (skimmer & strainer)

2. Not running the filter & pump long enough each day

3. Chemical problem

Lets discuss each.

If you have a sand filter, the sand may need to be replaced or just try getting the proper pool chemical and clean the sand first. Sand should be cleaned several times a season and changed every 3-5 years (this could vary depending on pool and chemical usage). If you have a cartridge filter, make sure you have a clean cartridge. If you have a DE filter, make sure you have enough DE Powder and that the grids are clean. Every time you backwash your DE filter, you should add the recommended amount of DE powder.

A lot of customers only turn their pump on at night. With high heat and humidity, the pool water will always look cloudy. If you have a continuous use pump, your filter system can run 24/7 during the summer. The more you filter the water, the cleaner it is going to be. With a chlorine generator, make sure the unit is in the right function to produce the proper amount of chlorine from salt.

Water chemistry is the most common reason for cloudy water. All these chemicals have to be in the proper range or cloudy water could be the result;

Chlorine reading- 1.5-2.0

PH- 7.4-7.6

Alkalinity- 110PPM

Calcium Hardness- 250 +

Stabilizer- 40 PPM

Please note that based on the chemical system you are using, these recommended readings may vary. If you bring a sample of your pool water to your local Medallion dealer, they can test it and give you the advice you need to eliminate cloudy water.
