Why is it Important to Have Your Water Balanced

You’ve probably heard that keeping water chemistry balanced is important. But why? What exactly does it mean, and how can you avoid a disastrous result? While this may seem like an unnecessary detail, balancing your pool water goes much further than just making sure your pH isn’t too high or too low.

Your water chemistry directly affects your swimming experience and the health of your pool. Imbalanced water can cause algae growth, scaling on interior surfaces, corrosion of metal parts, and even complete tile and plumbing failure. Keeping the correct balance of chemicals will not only help prevent these disasters from happening but also extend the life expectancy of your pool. These are some of the most important things to understand about water chemistry in swimming pools:

Which Chemicals Are Important When Maintaining Water Chemistry after a Swimming Pool Renovation?

You’ll need to test for several different things at different times of the year to make sure your water is balanced. pH: This is the level of acidity or alkalinity in your pool water and is measured on a scale from 1 to 14. pH levels between 7.2 and 7.8 are optimal for most pools, but yours may be slightly different. Alkalinity: This chemical level is also important for maintaining pH balance in your pool.

Like pH, alkalinity is measured as a scale from 1 to 15 and should be somewhere between 80 and 120 ppm. Calcium: This chemical level is important in preventing scale build-up inside pipes and walls. It can also help prevent the hardness of water. Calcium is measured in ppm, or parts per million. Chlorine: Keeping this level high will help keep bacteria and algae at bay. It should be between 1 and 3 ppm. Bromine – If you’re using bromine in your pool instead of chlorine, this is the level you’ll want to keep track of. It should be between 4 and 6 ppm.

What’s the Importance of Maintaining Water Chemistry?

Keeping your water chemistry balanced is important for several reasons. For example, a pool with low pH and high alkalinity will corrode metal parts much faster than a pool with balanced water. Corrosion can be prevented by maintaining a neutral pH level. Maintaining proper chlorine and bromine levels will help keep bacteria, algae and other pathogens at bay. Pool water that has been left unbalanced for too long will be very susceptible to algae growth. This can be a health hazard and must be dealt with immediately. Water that is not balanced will cause the pH of the water to be too high or too low, which can cause corrosion on the interior of your pool. Corrosion can lead to failure of your plumbing and metal parts.

Calcium, Chlorine and Bromine are also very important

If you’ve ever used a salt water pool, you’ve experienced the importance of calcium. The calcium content in the water acts as a buffer to keep pH levels in balance. Chlorine is also important in keeping bacteria and algae at bay. If you’re using a saltwater pool, you’ll need to make sure you’re adding the correct levels of calcium and chlorine. If you’re not monitoring these levels closely, you’re likely to see algae or bacteria growing in your pool. Bromine is another chemical that can be used in pools. It’s not as effective as chlorine in killing pathogens, but it does help to prevent algae. If you’re using bromine, you’ll need to keep close track of your levels to make sure you’re not allowing algae to grow.

Cyanuric Acid and Chlorine Retention

One chemical that you don’t have to test for is cyanuric acid. This chemical is added to pools as a chlorine stabiliser. It helps to extend the life of chlorine in the water and prevents it from being used too quickly by bacteria. Keeping your cyanuric acid levels high will help keep your chlorine levels from dropping too quickly. This will be helpful in preventing algae from growing in your pool. Keeping the chemistry of your water in balance is important to stop corrosion, stop algae from growing, and keep your pool clean and safe.

pH and The Importance of Water Buffering

One of the most important things to consider when balancing your water is the amount of water that is being used. If you’re using a lot of water and you haven’t balanced your pH correctly, you may end up with too much acidity. This may cause a chemical reaction in your pipes and leave them corroded. If you don’t have enough water in your pool and your pH levels are balanced correctly, you may end up with water that is too alkaline. This could cause corrosion on your interior surfaces. There are two ways to balance your pH. You can either add more acid or add more alkali. Incorrect alkalinity or ph can cause damage after a swimming pool restoration.

Alkalinity and Importance of a Buffer

A water buffer is something that helps to maintain pH levels in the water. It’s important to keep a certain amount of alkalinity in your water to act as a buffer. If you have a large amount of water in your pool, you may need to increase your alkalinity to balance your pH. If you have a small amount of water in your pool, you may need to decrease your alkalinity to adjust your pH. Being able to adjust your pH without changing the alkalinity in your water is important. You don’t want to create an environment where bacteria can thrive.


Pool water chemistry is important for many reasons. Keeping your water chemistry balanced will help prevent corrosion, prevent algae growth and keep your pool clean and safe. If your water chemistry levels are unbalanced, you can create an environment that bacteria thrives in. This could lead to your pool becoming contaminated with bacteria and swimmers getting sick from using your pool water.
