How Do You Lower Alkalinity but Raise pH?

If you own a pool, hot tub, or aquarium, then you already know that maintaining the pH and alkalinity levels is key to sparkling clear water. Keeping these levels balanced can be a bit tricky and often requires adjustments and knowledge on how to decrease alkalinity in a pool. 

If you’re struggling to keep your alkalinity and pH in check, you’re not alone. One question that many people ask is: how to lower your pool’s alkalinity but raise pH levels? It’s important to know the answer to this question, as well as to achieve the perfect balance for your pool.

Why Are Alkalinity and pH So Important?

pH is the measurement of the acidity or basicity of your pool water, and it’s vital in keeping swimmers comfortable and equipment functioning properly. Are you wondering if you can swim with low pH and alkalinity? When the pH is too low, the water becomes acidic, which can cause skin irritation, corrosion of metal, and even etching of the pool walls. 

On the other hand, when pH is too high, the water becomes alkaline, causing skin irritation and cloudiness. Alkalinity is the measure of the concentration of alkaline substances in the pool. It stabilizes the pH level to prevent harmful swings in pH levels. 

Essentially, maintaining balanced pH for pool alkalinity is critical for pool health and the safety of swimmers. 

Why Reducing One Influences The Other

Alkalinity and pH are closely related, and changes in alkalinity levels can have a significant impact on pH. You may have noticed while trying to adjust your pH levels that they keep increasing or decreasing, no matter how much acid or base you add. That’s because if your alkalinity is too high, it will push your pH levels higher as a result.

Conversely, if the alkalinity is too low, it will be difficult to maintain the pH level. In other words, reducing the alkalinity will eventually influence the pH level in the same direction.

Steps to Achieve the Perfect Chemical Balance

Here is a step-by-step guide for achieving the perfect balance of your pool water:

Step One: Test Your Water

Testing your pool water is the first step to determining your chemical starting point for your pool type, size, and water temperature. You can use a water testing kit or hire a pool professional like the Pool Care Guy to check and analyze your pool water.

Step Two: Add pH Increaser

For most pool owners, adding a pH increaser is the easiest way to raise your pH level. You might need to add a small amount at a time, depending on your pool size and the initial pH level measured. Wait for about four hours and then test the pH level again. Repeat until the desired level is reached.

Step Three: Add Alkalinity Reducer

Once you’ve successfully raised your pH level, we can now move to lower your alkalinity. Add an alkalinity reducer product, following the manufacturer’s instructions. Allow time for the product to dissolve before testing the water.

Step Four: Retest Your Water

Allow your pool to circulate, then recheck your water levels. The alkalinity level should have dropped while maintaining the pH level. If you still haven’t achieved the desired levels, repeat the steps above until you do.

Step Five: Maintenance

After you’ve attained the perfect alkalinity and pH levels, maintaining the balance requires regular checks, adding chemicals, and keeping an eye on the water temperature, rain, sun exposure, and bather load.

Maintain Water Quality

Maintaining the balance between alkalinity and pH levels in your pool is critical to the health of the swimmers and your equipment. Reducing alkalinity levels without changing your pH level can be a challenging ordeal, but understanding the relationship between the two will help you achieve the perfect balance required for crystal-clear water. 

Remember to test regularly, add chemicals in the correct amount, and maintain your equipment to ensure a safe and enjoyable swimming experience in your backyard oasis!
