How to Maintain Pool Water Chemistry
We all love swimming. Don’t we?
In the scorching summer, spending a few hours in the swimming pool with family is heavenly. In those moments of leisure, both our body and mind feel relaxed. But this joy is also instantly obscured if we do not take care of our pool water chemistry. According to study and research, many harmful chemicals found in the water can make us sick, therefore it’s necessary to keep track of and properly maintain the pool chemical levels.
What types of chemicals are found in the pool water?
Pool Chemical levels Checklist
● PH Level
● Free Chlorine (FC)
● Combined Chlorine (CC)
● Calcium hardness (CH)
● Total Alkalinity (TA)
● Cyanuric Acid (CYA)
Maintaining proper PH balance in the pool keeps the water sparkling clean, but it also helps defends our system components from damage and can help our pool look like new. One of the most important elements of that balance is the PH level.
The PH level of pool water indicates its acidity. It is noted on a scale of 0 to 14, with a PH below 7.0 would indicate that the water is acidic. A PH of 8.0 means that the water is basic or alkaline. The appropriate pool PH level between these two points is 7.4 to 7.6. On this basis, we can decide how much PH we need to increase or decrease.
Free Chlorine (FC)
Free chlorine (FC) Available in bottles, 3-inch tablets, 1-inch tablets, sticks, and a granular form. Chlorination of water is considered the most reliable reagent method of disinfection and is based on the addition of chlorinated substances to water. Among the merits of this method can be noted: science, long-term action and guaranteed disposal of most pathogens known for a cheap cost. Free chlorine (FC) should be between 1 and 3 ppm.
Disadvantages of a higher level of FC in Pool: There is a constant need to deal with the toxic water formed in chlorination products, the inability to eliminate chlorine from microorganisms and “habituate” pathogenic microbes to a certain level of chlorine in the water. Confirm free chlorine (FC) to be majorized through the test kit. Look for chlorine tablets or sticks with 90% concentration of Trichloro-S-Triazinetrione.
Combined Chlorine (CC)
When chlorine oxidizes and combines with nitrogen compounds, there is no longer free chlorine (FC). It is being said, the combined chlorine. Combined chlorine (CC) is easy to measure. Just measure the total chlorine (TC) and deduct free chlorine (FC) from it. It is a measurement of chlorine in the pool as it is no longer free and available.
TC – FC = CC
Common warning signs of a higher level of CC in Pool:
● Itchy and red eyes
● Irritation in the nose and throat
● Dry hair and itchy skin
● Some breathing problems
We can maintain the level with shock treatment. Either chlorine or a non-chlorine sanitizer will secure the destruction of the nitrogen compound combined with the chlorine and that will maintain the best level in our pool.
Calcium hardness (CH)
Such water is called hard water, which is rich in mineral salts. It contains bicarbonate and carbonate of calcium and magnesium. Its simple identity is that it does not produce froth with soap. Keep in mind that ‘heavy water’ is a different thing. However, a much higher level of calcium carbonate and magnesium minerals in the water is called Calcium hardness (CH).
A recommended level of calcium hardness is 200 to 400 ppm. Both high and low levels result in pool water and health problems, such as skin-related disorders and hair loss problems due to the use of hard water and Calcium hardness.
To maintain proper levels, replace some or all of the pool water to reduce calcium hardness levels. If the reason is water, then commercial hardening agents or strangling agents will bind with calcium to fix it in the solution.
Total Alkalinity (TA)
Total Alkalinity (TA) is a value of the total alkaline substances found in pool water. In swimming pools, we usually determine the calcium carbonate content of water by measuring its levels. It should be maintained in between 80-120 ppm for swimming pools.
High total alkalinity reduces PH sensitivity. The result is typically higher PH and lower chlorine efficiency. This can also result in scale formation and cloudy water. Low alkalinity increases the sensitivity to PH. Water with a low alkalinity level can rapidly move from a high PH to a low PH and then return. This is called PH bounce back and can be harmful to pools, health, and equipment.
By using the Pool Pro Buffer, we can maintain its best levels.
Cyanuric Acid (CYA)
Cyanuric acid is known by many different names in the pool industry, such as CYA, pool conditioner, pool stabilizer or chlorine stabilizer. Whatever we choose to call it, this chemical has played a constitutional part of pool maintenance since its invention in 1829. The main purpose of this invention is to help stabilize chlorine levels and allow it to protect from UV rays, while sanitizing the pool for a longer period. Its purpose is to freeze the chlorine in the pool, so the sanitizer stays longer, keeping pool water cleaner for longer.
The WHO (World Health Organization) gives guidance of an upper limit of 100 ppm of cyanuric acid as a recommended amount for your pool. This number is founded upon the realization that kids swimming in the pool may ingest some water, but if they swallow too much cyanuric acid, it can make them very ill. So, it’s best to keep the CYA to approx. 50 ppm. For health safety purposes, any high concentration will prevent the chlorine from forming bacteria and/or algae growth. So, always remember that increasing the protection from UV rays is not necessary for CYA.
Additional Chemicals to increase or decrease the prescribed levels of different chemicals and their effects.
● PH Increaser: Sodium Carbonate, Soda Ash
● PH Decreaser: Sodium Bisulfate
● Alkalinity Increaser: Sodium Bicarbonate, Baking Soda
● Alkalinity Decreaser: Muriatic Acid, Sodium Bisulfate
● Calcium Hardness Increaser: Calcium Chloride
So, friends, I hope that whenever you will enjoy your summer holidays with your family at your swimming pool, you will take care of pool water chemistry levels for our health purpose as well as to make our pool a safe place to be relished our leisure.
