Although it can feel a little intimidating when maintaining the proper balance in your pool, you don’t need a science degree to get that crystal clear water. Here are the basic steps to balance the water chemistry of your pool.

Although it can feel a little intimidating when maintaining the proper balance in your pool, rest assured, you don’t need a science degree to get that crystal-clear water. The right chemistry helps each substance in your pool last longer, preserves your pool’s structure, and creates a more enjoyable swimming experience. To help you get started, here are the basic steps to balance the water chemistry of your oasis.

What is Pool Water Chemistry Balancing?

Water chemistry balancing is the practice of harmonizing various chemical factors within your pool to ensure it remains a safe and inviting oasis. It’s not just about achieving clear water; it’s about safeguarding the well-being of those who swim in it.

At its core, this process involves adjusting parameters like pH levels, chlorine concentration, alkalinity, and calcium hardness. Each of these factors plays a unique role in maintaining water quality.

The Importance of Water Balancing

First, let’s clarify why balancing your pool’s water chemistry is so important. Keeping factors like the pH, total alkalinity levels, and calcium hardness in check will prevent damage to your pool and allow you to maintain safe, clean, and comfortable water for swimming. 

Balancing each of these prevents several issues with your pool, including corrosion of the equipment and surfaces, formation of algae, scale, stains, and cloudy or discoloured water. Unbalanced levels can also lead to irritation of the skin and eyes after swimming.

How Often Should I Test the Water?

If the chemicals aren’t yet balanced, it’s important to check the pool water every day until you achieve the proper levels. Adjust accordingly if necessary. If the water is balanced, the pool water should be monitored using a test kit every week during the summer months. This frequency ensures you catch any imbalances early, preventing minor issues from snowballing into bigger ones. Additionally, it helps you fine-tune your chemical adjustments with precision.

However, keep in mind that testing isn’t limited to weekly routines. Depending on certain circumstances, you may require further testing, such as after heavy rain, pool parties, or any significant influx of swimmers. These events can disturb your pool’s equilibrium, and timely testing allows you to restore it quickly.

Steps to Follow For Proper Water Balance:

With some simple and easy guidelines, you’ll be well on your way to maintaining your pool’s chemistry. Here’s how to get started:

1. Switch on the Pump

Always ensure the pool pump is turned on before you begin the balancing process. This will help the chemicals disperse throughout the water.

2. Test and Adjust Total Alkalinity

Once the pool pump is on, it’s time to test the water’s total alkalinity or alkaline material. Total alkalinity measures the water’s resistance to changes in pH. In simpler terms, it acts as a buffer, preventing your pool’s pH levels from getting too extreme. 

The goal is to achieve a range of 80 to 120 ppm. If it’s higher than that, you’ll need to lower it by adding muriatic acid or sodium bisulphate. If the level is too low, you’ll need to add sodium bicarbonate.

3. Test pH Level

The pH level is important for preventing the pool water from damaging any surrounding surfaces. It shows you how acidic or basic the water chemistry is. The goal is to maintain a pH level of 7.4 to 7.6. If your pH level is too high (alkaline), you might see cloudy water and scaling. If it’s too low (acidic), you risk corrosion and skin and eye irritation.

You can adjust the levels by using a pH increaser (sodium carbonate) or a decreaser (sodium bisulphate or muriatic acid). If your tests show that the pH level isn’t steady, this can indicate an imbalance with the total alkalinity level.

4. Measure Calcium Hardness

This measurement determines the concentration of calcium ions in your pool water, helping prevent consequences like plaster damage or scaling.

If a white line starts to form along the waterline, there is likely too much calcium in the water. If this isn’t corrected, it will continue to stain the pool and eventually impact the equipment. The correct calcium hardness level you want to achieve is between 200 to 400 ppm.

You’ll need calcium chloride to increase the level. To decrease, drain a portion of the pool water and replace it with fresh water. If the calcium build-up is significant, you may need a pool vacuum to remove any lingering residue.

5. Sanitize the Pool

With the foundational aspects of water chemistry addressed, it’s important to remember one of the most critical aspects of pool cleanliness and safety: sanitation. The primary role of sanitizers is to kill and inhibit the growth of harmful microorganisms like bacteria and algae. These unwelcome guests can turn your pool into a breeding ground for illness and unsightly green water.

There are several types of sanitizers, including bromine, biguanide, minerals, chlorine and shocking the pool. The most common is chlorine. The ideal level of chlorine is three ppm; however, this level may need adjustment depending on factors like pool usage, weather conditions, and water temperature. 

Shocking the pool is also recommended to help refresh the water. This method adds a highly concentrated dose of chlorine to the pool to rapidly increase the chlorine level in the water. The “shock” helps break down contaminants, control algae and bacteria, and restore balance. Follow the instructions on the chemical’s label carefully when doing this.

6. Check Cyanuric Acid

Cyanuric acid, often referred to as a pool stabilizer or conditioner, plays a vital role in maintaining water quality. It is usually included in the shocking process. Cyanuric acid serves as a shield for your pool’s chlorine, helping prevent the sun’s UV rays from rapidly breaking down the chlorine molecules in your water. Without adequate cyanuric acid, chlorine would dissipate quickly, making it challenging to maintain a consistent sanitizer level. The proper level you want to achieve is 30 to 50 ppm.

7. Measure Total Dissolved Solids

Finally, it’s time to measure the total dissolved solids (TDS) in your pool. TDS refers to all the substances that have dissolved in the water, including but not limited to dirt, algae, minerals, chemicals, and small debris particles. Measuring TDS is important because it provides insights into the overall water quality and helps make informed decisions about when it’s time for corrective action. 

The acceptable level is typically near the 1,000 ppm mark and below 2,000. If it’s higher than 2,000, drain and add in fresh water. Generally, high TDS can lead to issues like cloudy water, reduced sanitizer effectiveness, and even damage to pool equipment and surfaces. Additionally, high levels may affect overall pool comfort—it may feel harsh on the skin, irritate the eyes, and or lead to an unpleasant odour.
