How To Raise pH in a Hot Tub Without Chemicals

To raise pH in your hot tub without chemicals, you can explore natural methods. These tactics are gentle on the environment and safe for your skin. The pH level is important for comfortable and clean hot tub water.

Low pH levels cause the water to become acidic, which can irritate your skin and eyes and damage the hot tub’s components.

Natural approaches to adjusting pH can ensure your hot tub stays in great condition without relying on synthetic hot tub chemicals. They can also maintain water clarity and prevent damage from acidity.

pH Levels in Hot Tubs

Maintaining the right hot tub pH level is essential for both your comfort and the longevity of the tub. But what exactly is pH? It measures how acidic or alkaline your hot tub water is. The pH scale ranges from 0 to 14.

Here's a simple breakdown:

• Acidic: Below 7.0
• Neutral: Exactly 7.0
• Alkaline (Basic): Above 7.0

For your hot tub, you want to keep a balanced pH level, which is typically between 7.2 and 7.8. This means the water is slightly alkaline. When the pH is just right, it helps protect both your skin and the hot tub equipment.

If your pH dips below 7.2, the water becomes too acidic. It can irritate your skin and eyes and even damage the hot tub parts. On the flip side, it becomes too alkaline if the water climbs above 7.8. This can cause cloudy water and scale buildup.

pH Levels and Adjustments

To check the pH levels, you'll use test strips or a test kit. Just dip the strip into your hot tub water and compare the color change to the chart provided with the test. It's easy and takes only a minute.

Remember, when you adjust the pH, you might also affect the total alkalinity (TA). Aim to keep your TA levels between 80 and 120 parts per million (ppm). TA acts as a buffer; it helps keep the pH level stable.

Handle pH adjustments gently. Make small changes and test often. This avoids sudden swings in pH that could make your hot tub time less enjoyable.

Natural Methods to Raise pH

‍

Your hot tub is a place for relaxation, and keeping its water in perfect balance is key. A proper pH level ensures your hot tub water is safe and pleasant. Here's how you can do this naturally:

Baking Soda (Sodium Bicarbonate)

You likely have baking soda in your kitchen. It's not just for baking; it's a natural way to add alkalinity to water, which in turn can help raise the pH. This method also helps to raise alkalinity, ensuring balanced water chemistry.

Steps to Use Baking Soda:

1. Test the Water: Check your hot tub water to know the current pH level.
2. Calculate Amount: Determine the amount of baking soda needed based on your hot tub's volume.
3. Dissolve First: Dissolve the baking soda in water before adding it to the hot tub to ensure even distribution.
4. Add Gradually: Go slowly, adding baking soda in increments, and keep testing the pH after each addition until you reach the desired level.

Borax

Borax also raises pH levels by increasing the water's alkalinity. Follow the same steps as with baking soda, and always test the pH level after each addition. These natural methods effectively raise pH levels without synthetic chemicals.

Unlike baking soda, borax doesn't affect total alkalinity as much, making it a good option if you've got the alkalinity right but need to tweak the pH slightly.

Remember, adjustments to your hot tub water should be gradual. Always retest the water after each treatment to avoid overshooting the ideal pH range.

Sodium carbonate is another name for soda ash, which is commonly used to raise pH levels in various water treatments.

"We got a Hot-Tub just over a year ago, which I initially loved, but due to having very sensitive skin, I was using it less and less as using chlorine was causing me to have itchy skin, so I basically used it less and less and then not at all. My wife continues to use it almost everyday without a problem so it was definitely my issue. Someone told me about O'Care and I started to use it approx 2 months ago and what a difference. No Itchiness to the skin, no chlorine smell and coming out with a silky skin that feels moisturized." - Colin Torley on Trustpilot

Practical Example

Assume your hot tub's pH is currently at 6.8, and you want to raise it to within the ideal range of 7.2 - 7.8:

1. Small Adjustment:some text
   • Scenario: The current pH is 7.0, and you want to raise it to 7.2.
   • Action: Add 1 - 2 tablespoons of baking soda for a 500-gallon hot tub.
   • Expected Outcome: The pH should increase by about 0.1 to 0.2 units.
2. Large Adjustment:some text
   • Scenario: The current pH is 6.8, and you want to raise it to 7.4.
   • Action: Add 16 tablespoons (1/2 pound) of baking soda for a 500-gallon hot tub.
   • Expected Outcome: The pH should increase by about 0.5 to 1.0 units.

Influence of Water Source on pH Levels

When you fill your hot tub, the water source plays a key role in the initial pH level. Tap water usually has a pH close to neutral, which is a pH of 7. This can vary if your water comes from a well, it might be more acidic or more alkaline. This variation means the pH could be below or above 7.

Why does this matter for your hot tub? Water that starts off with a low pH could lead to the need for constant adjustments. Acidic water can corrode parts of your hot tub and make your soak less comfortable.

Here’s a tip: Always test the pH of your water source before adding it to your hot tub. You can use pH strips for a quick check. If the pH is too low or too high, you'll be prepared to make adjustments.

• City Water: Usually treated and tends to be neutral.
• Well Water: Can vary greatly and often leans toward being more acidic or alkaline.

‍

If your source water is outside of the recommended range, you'll have to treat it more often.

Environmental Factors Affecting pH

A range of environmental factors can influence our hot tub's pH level. Keeping these in check helps maintain a natural balance in your spa's water.

• Rainwater: When rain falls into your hot tub, it can lower the pH. Rain is slightly acidic and can introduce contaminants that affect pH levels.
• Organic Materials: Leaves, grass, and other natural debris contribute to pH changes. They decompose and release acids into your hot tub water.
• Sun Exposure: The sun's UV rays can break down chlorine in your hot tub, which can cause fluctuations in pH levels.

‍

Water Source: Tap water varies in pH balance. Test the pH of your tap water before adding it to your hot tub.

Here's a quick table to summarize:

Frequently Asked Questions

How do I correct low pH in my spa without raising alkalinity?

To raise pH without affecting alkalinity, you can aerate your water. Aeration involves increasing the water's exposure to air, which can be done by turning on jets or water features. This process does not add chemicals to the water but can help increase pH levels.

What should I do if I notice skin irritation after using my hot tub with low pH?

If your skin feels irritated after using the hot tub, test the water's pH first. A low pH can cause discomfort. To raise the pH, you can add a natural pH increaser like baking soda. Add about one tablespoon for every 100 gallons of water and retest the water after a few hours.

Is it possible to use household items like vinegar to modify the pH in my spa?

While vinegar can lower pH, it's not recommended for increasing pH levels. Vinegar is acidic and would further decrease the pH. Instead, you should use baking soda or aeration techniques to raise the pH naturally without harsh chemicals.
