Various chemicals are used in your swimming pool that you have used before and heard of before, but never truly known what the chemical is all about. Here’s your chance to get close and personal with some of these chemicals u deal with everyday!
1) pH Control: pH stands for Potential Hydrogen (who’d have thunk it?). pH is the measure of the acidity or alkalinity of your swimming pool water. The ideal pH level of your swimming pool is between 7.3 – 7.8. If the pH level of your swimming pool water is higher than 7.8 the water will be cloudy and will result in scale buildup, filtration problems, deposits in the water and a decreased efficiency of the chlorine. On the other hand, if the pH level falls below 7.2, this will lead to the corrosion of metallic pipes and rapid loss of chlorine residual which may lead to irritation to the swimmers. Use increasers or decreasers as need be to keep your pH level in control. Click here to find the best increasers or decreasers for your pool.
2) Calcium hardness: Calcium hardness refers to the amount of calcium that has dissolved in your swimming pool water. The ideal amount of calcium dissolved in your swimming pool is between 100 – 500 PPM. A PPM above 500 will cause the water to become cloudy and a low PPM will result in corrosion to your swimming pool equipment and pipes. Add a rust and scale remover to prevent cloudy water and add water hardness increaser to correct a low water calcium level. We recommend a bottle of Applied Bio Staintrine.
3) Chlorine: The most often heard about chemicals when talking about swimming pools is chlorine. While this is the most widely used chemical in swimming pools, it is not the only one! Nor is chlorine chemistry as easy as saying the word ‘chlorine’! Most obviously chlorine is a disinfectant. But it has to be used in the proper way with the proper desired quantity so that it works efficiently while at the same time not causing irritation to the swimmer.
The most common form of chlorine that is used in swimming pools is calcium hypochlorite which contains 70% chlorine. the desired free released chlorine level of your swimming pool water is between 1 and 2 ppm. If all the above factors, total alkalinity, pH level and calcium hardness are in their respective desired zones, you will have to worry less about disease and extra cost in the long run. So one may now ask what this word ppm we keep coming across is. Ppm simply stands for parts per million.
The way that chlorine is consumed in the swimming pool also depends on various variables:
- Chlorine dissolves fasters in warm water than in cold water
- Sunlight causes an increase in the rate of chlorine consumption
- Presence of bacteria and debris also increases the amount of chlorine consumed. Even if a pool looks sparkling clean, the swimming pool water does contain bacteria that enter the pool on bathers’ skin.
It now seems obvious why more chlorine is added on hotter days than on cooler days doesn’t it!
How to use chlorine in your swimming pool water:
Chlorine is added to the swimming pool water by the means of a chemical feeder or dispensing tablet. NEVER MIX CHLORINE WITH ANY OTHER CHEMICALS!!
There are various different forms that you will hear the word chlorine in. following is a simple summary:
Total chlorine: The sum of the amount of free chlorine and combined chlorine.
Free chlorine: The active chlorine that actually kills the germs and bacteria in your swimming pool and keeps it clean.
Chlorine: The most commonly used chemical to kill bacteria in your swimming pool.
Chlorine demand: All the alien materials in your swimming pool that use up the chlorine – algae, debris, bacteria.
Chlorine residual: This is the amount of chlorine that is left in your swimming pool after the chlorine demand has been fulfilled.
Chloramines: chlorine after impurities have been oxidized. This form of chlorine does not help in disinfecting your swimming pool water.
4) Algae: Algae are the small plants that grow on the walls and floor of your swimming pool. Algae causes the walls and floor to become grimy which in turn makes the water cloudy and increases the pH of your swimming pool water. that is why it is extremely important to check your swimming pool water very often, at least once a day so that the pH level can be corrected right away by using the appropriate increasers, decreasers or kits. Algae grows best on very hot days. This is due to the fact that more chlorine is consumed on hotter days and sunlight is always good for any living things! So it is even more important to check your swimming pool water on hotter days with the appropriate kits. If you already have a problem with algae, then there are 2 options available to you.
- Use shock treatment: shock treatment is adding 5 – 10 times the amount of normal chlorine which in turn shocks the water and helps kill bacteria and algae
- Use algaecides.
