1. What is the Borax Pool pH Formula?

The Borax formula calculates the amount of borax (sodium tetraborate) needed to raise the pH level in swimming pools. Borax is an effective pH buffer that helps maintain proper water chemistry without significantly affecting total alkalinity.

2. How Does the Calculator Work?

The calculator uses the borax formula:

Where:

• \( V \) — Pool volume in gallons
• \( \Delta pH \) — Desired pH increase in pH units
• 1.5 — Conversion factor for borax

Explanation: The formula calculates the ounces of borax needed based on pool volume and desired pH increase, using a standard conversion factor.

3. Importance of pH Adjustment

Details: Maintaining proper pH levels (7.2-7.8) is crucial for swimmer comfort, effective chlorine disinfection, and preventing damage to pool equipment and surfaces.

4. Using the Calculator

Tips: Enter pool volume in gallons and desired pH increase. Always test current pH level before adding chemicals and add borax gradually, retesting after several hours of circulation.

5. Frequently Asked Questions (FAQ)

Q1: How often should I test my pool's pH?
A: Test pH at least twice weekly during swimming season, and after heavy use or rainfall.

Q2: Can I use baking soda instead of borax?
A: Baking soda primarily raises alkalinity with minimal pH effect, while borax raises pH with minimal alkalinity effect.

Q3: Is borax safe for all pool types?
A: Borax is generally safe for all pool types but consult your pool manufacturer's guidelines, especially for vinyl liners or specialty finishes.

Q4: How long does it take for borax to affect pH?
A: Allow 4-6 hours of circulation after adding borax, then retest before adding more.

Q5: What's the maximum safe pH increase at one time?
A: Don't raise pH more than 0.4 units at once to avoid overcorrection and potential cloudiness.
