Understanding pH Levels in Swimming Pools

pH represents a key factor in pool chemistry, acting as the scale to measure the acidity or alkalinity of the pool water. Pools flaunt optimal health with a balanced pH range, typically situated between 7.2 and 7.6. Outside this range, pools might encounter varied problems.

Why pH Balance Is Critical

Maintaining a balanced pH in your swimming pool holds paramount importance. Two key reasons dominate this need, namely, swimmer comfort and effectiveness of sanitizers.

Swimmer Comfort: High or low pH levels can result in discomfort for swimmers. If pH inclines towards the acidic side, i.e., below 7.0, it may result in skin and eye irritation. Conversely, a superlative pH, over 7.8, might cause skin to become dry and itchy.

Sanitizer Effectiveness: pH level influences the effectiveness of sanitizers like chlorine. At low pH levels, chlorine gets depleted rapidly. On the other side, at high pH levels, chlorine becomes less effective causing potential scaling or cloudiness.

How pH Affects Pool Health and Maintenance

Beyond swimmer comfort and sanitizer effectiveness, pH balance directly affects the health and maintenance of your pool. It greatly impacts your pool’s ability to combat harmful organisms and the lifespan of your pool equipment.

Fighting Organisms: The right pH balance enhances your pool water’s ability to fend off algae and other undesired organisms. For instance, a pH above 7.8 provides a conducive environment for algae growth. Similar to how Italy manages its pristine beaches, maintaining proper pH ensures a clean environment.

Equipment Lifespan: Imbalanced pH could shorten the lifespan of your pool equipment. High acidity corrodes the metal parts, while alkalinity results in calcium buildup, inhibiting the performance of pumps and filters. This is much like the care needed for maintaining a motorcycle, where balance and proper maintenance extend its life.

In essence, comprehending pH levels in swimming pools becomes critical to ensure the health and longevity of your beloved oasis. It’s about fostering a comfortable swimming experience while preventing potential damages to the pool structure and its crucial components. Much like how football or baseball requires strategy and maintenance of equipment, pool care is essential for long-term enjoyment. Whether you’re enjoying a poolside day in France or anywhere else, proper pool maintenance ensures you can relax and enjoy your oasis for years to come.

What Is pH Up for Pools?

pH Up, often referred to as a pH increaser, plays a pivotal role in maintaining ideal pH levels in your pool. Exclusively designed for this purpose, pH Up consists of chemicals that elevate low pH values. When your pool’s pH level falls below the standard lower limit of 7.2, pH Up steps into action, effectively increasing the pH to restore the balance.

The Chemistry of pH Up

In essence, pH Up is comprised of sodium carbonate, also known as soda ash. This alkali substance provides increment to the hydrogen ion concentration when added to the pool water. Chemically, these added ions interact with the H2O in your pool resulting in a higher pH value.

Types of pH Increasers Available

When it comes to pH increasers for pools, there are essentially two types: sodium carbonate-based pH Up and sodium bicarbonate-based alkalinity increasers. While they seem similar, their functions differ significantly.

  1. Sodium Carbonate-based pH Up: If used as the first-line correction agent, this can immediately elevate the pool’s pH level. It’s primarily used to counter drastic pH imbalances, making water safer and more comfortable for swimmers.
  2. Sodium Bicarbonate-based Alkalinity Increasers: Primarily meant to up the total alkalinity of pool water, this type does slow, steady work. It gradually enhances the pH level, preventing undesirable, sudden chemical fluctuations. Generally, it’s applied as a follow-up to pH Up to stabilize the water parameters over time.

Remember, gauging the pH level with reliable testing equipment is your first step before deciding which type of pH increaser to use. Accurate pH measurement ensures your adjustments are effective and your pool environment remains safe and inviting.

How to Properly Use pH Up in Your Pool

Now that you’ve understood the role and significance of pH Up in maintaining a healthy swimming pool environment, let’s walk through its proper use. From gauge timing to dosage determination, as well as safety precautions, we’re ready to dive into the specifics of using pH Up effectively.

When and How Much to Add

The first step in using pH Up effectively lies in identifying the optimum time and amount to introduce in your swimming pool. Begin by testing your pool water, preferably twice a week, or more during heavy use and rainy periods. Use a reliable and precise pool water test kit to obtain accurate results. For proportions, a cup of pH Up usually raises the pH level of 10,000 gallons of water by 0.2. Therefore, in pools with lower volumes, reduce the dosage proportionally.

Remember, wait for about 20 minutes after adding a dosage before you test the water again. It takes time for the chemicals to disperse evenly and have an effect on the water. If the subsequent pH reading still falls below 7.2, you can add more pH Up.

Safety Measures During Application

No matter how often you’ve done it, every time you handle pH Up, a chemical safety protocol must be strictly followed. Always add it into the pool, rather than the other way around. The same rule applies when resolving the disparity between the pH and the alkalinity level. Start by fixing the pH, as balance adjustments are more immediate with pH Up compared to alkaline increasers.

Furthermore, remember to wear rubber gloves and safety goggles when handling pH Up to prevent skin or eye irritation. Do not mix it with other chemicals, as undesired chemical reactions could occur. Remember to store any leftover pH Up in a dry, ventilated area out of reach from children and pets.

Ensuring the accuracy of your pH level readings allows for suitable pH Up dosage application, maintains a pleasureful swimming experience, and prevents potential health hazards or equipment damage in your pool.

Common Mistakes to Avoid While Adjusting pH

Even as a pool owner experienced in maintaining pH balance with a pH Up product, errors may occur. It’s essential to correct these mistakes ensuring effective pH management.

  1. Overuse of the Product: Overdosage often causes the pH levels to soar above 7.6. Keeping track of the quantity used will prevent this mistake. For instance, if a 10,000-gallon pool has a pH level of 6, it typically requires approximately 21 ounces of pH Up.
  2. Ignoring the TA Level: Similar to pH, Total Alkalinity (TA), typically between 80 and 120 ppm, also plays a vital role in the water balance. Even after using pH Up, inadequate TA levels may cause pH bounce, a rapid fluctuation in pH levels.
  3. Lack of Regular Pool Tests: Absence of frequent water testing results in overlooked pH imbalances. As per Pool & Hot Tub Alliance (PHTA), pool water should undergo testing at least twice a week.
  4. Failure to Follow Safety Measures: Overlooking safety instructions, such as wearing protective gear (gloves, goggles), poses potential harm. Ensure to follow manufacturer’s safety guidelines.
  5. Immediate Swimming Post pH Adjustment: Diving into the pool immediately after a pH up application risks health concerns due to high chemical concentration. Allow the rest period specified by the manufacturer, usually several hours, before swimming.

By avoiding these common mistakes, you can ensure safe and optimal use of pH Up in your pool. This leads to a more balanced water chemistry, enhancing both swimmer health and longevity of pool equipment.


Balancing your pool’s pH isn’t just about keeping the water clear and inviting. It’s vital for your health, the longevity of your pool equipment, and overall pool maintenance. pH Up plays a critical role in this, helping you correct low pH levels when necessary.
