A proper balance of chemical is required to keep a swimming pool safe for swimmers. Proper maintenance of a pool saves the owner time and money. When it comes to maintaining the water chemistry in a swimming pool, there are many things that pool owners need to consider.

Hardness level of water

Maintaining proper water hardness level is an essential part of the water chemistry. It is the first step in maintaining the chemistry of pool water. Hardness in pool water is a result of the partial minerals present in the water supply. Blue Tongue Property and Maintenance help to design your pool landscaping.

The hardness level is usually different for different pools depending on the source of water supply.  Your pool water also becomes hard as a result of the chemical compounds you add for its treatment. Pool owners should maintain the water hardness level between two to four hundred parts per million.


It is crucial to test the alkalinity of your pool water regularly. Alkalinity is usually measured in terms of pH level. The low pH levels indicate that your water is acidic and high pH level indicates that the water is basic. Rainwater and anything that enter the pool water can affect the alkalinity of water.

Always keep an alkalinity enhancer or pH increaser on hand as you need it frequently to maintain the alkalinity of water. Every pool owner should maintain the pH level of the pool water between 7.4 and 7.6 which is the ideal level of alkalinity for swimming.

Calcium Hardness

It is vital to maintain the calcium hardness in your pool water. The lack of calcium hardness in the pool water protects the plaster and pool equipment from damage. The calcium level should be optimal as too much calcium can lead to deposits and too low levels can damage your plaster.

 Pool owners should maintain the calcium hardness between 220 and 350 parts per million. Proper calcium levels protect the walls and pool equipment in the long term. If the calcium hardness is low, you can add calcium to it, but in case of high levels, you need to drain some water and refill the pool with fresh water.


Chlorine is a cost-effective solution against the harmful bacteria and algae. There are many ways to add chlorine into the pool water as you can add chlorine tablets or granular chlorine. Also, there is a salt chlorine generator that converts table salt into chlorine.

The most common form of chlorine is in the form of tablets. You can add the chlorine tablets or granules to the chlorine dispenser or the chlorinator or the skimmer basket of your swimming pool. Buy the chlorine having dichloro or trichloro as the active ingredients as they are the stabilised chlorine products. UV rays from the sun deteriorate the chlorine quickly, but these ingredients slow down the process.

Pool Shock treatment

Pool shock is another term used for the treatment of pool water. Shock is required when the pool is frequently used or after a pool party which contaminates the water and unbalances its chemistry. When the chlorine particles attack or kill the bacteria or any other organic materials in the water, they are known as combined chlorine. They stay in the water until they are oxidized which needs shock treatment

Shock treatment involves adding high levels of chlorine. The shock treatment products use unstabilized chlorine for treatment of pool water. The ingredients enter the water, clean it and are eaten by the UV rays from the sun. That is who pool care experts recommend shocking the pool water at night and let it do its job throughout the night.


Algae is the green colored stuff that builds up in your pool is not cleaned regularly. It is caused by the rainwater, debris and bird droppings that enter the water. Adding algaecide prevents the building up of algae on the walls and surface of the water. However, if the algae had already built up on the sides, you need to clean it up with a scrubber brush and then add algaecide to your pool.

Cyanuric Acid

Cyanuric acid is another important chemical that you need to add to your pool which protects the chlorine from the UV rays of the sun. It acts as a stabilizer base to protect the chlorine in pool water. It is essential to maintain the Cyanuric acid level between 30 and 50 in the pool, which protects the chlorine and let it stay to kill the bacteria and other germs in water.


Biguanide is an alternative to chlorine and an effective sanitizer. It cleans the water and makes it feel smooth. The pool sanitizers of major brands contain Biguanide, and you may not need to add it separately. It is best to use a complete package of chemicals offered by a reliable brand. These chemical packages are usually available in liquid form and are expensive than the regular chemicals.

Clarifier and Floc

A water clarifier brings the tiny particles together that makes your water cloudy. It combines such tiny particles to form the bigger particle, which the pool filter can easily filter out. A floc or flocculant collects the tiny particles, and they sink at the bottom, which can be cleaned manually by pool vacuum.

Schedule a yearly service
Other than adding the right chemical to your pool, you need to examine and maintain the equipment of your pool. If you know about the equipment, you can check it yourself, or contact a pool care expert to get it examined. It is best to check the pool care equipment every season and perform the repair or replacement of damaged components.

Final words
In addition to maintaining the pool chemistry, you also need to check and maintain the health of pool equipment. Good filtration and circulation of water are essential to keep it clean and hygienic for swimming. Make sure you install high-quality equipment like the ONGA ppp1100 Pumps which circulates the water effectively. It is best to call a pool expert while adding chemicals to the pool and maintain their optimal levels.
