1. What Is Borax And How Does It Raise Pool pH?

Borax (sodium tetraborate) is a common household product that can be used to raise the pH level in swimming pools. It acts as a pH buffer, helping to stabilize the water chemistry and prevent rapid pH fluctuations.

2. How The Calculator Works

The calculator uses the borax formula:

Where:

• \( V \) — Pool volume in gallons
• \( \Delta pH \) — Desired pH increase in pH units
• 1.5 — Standard multiplier for borax calculation

Explanation: This formula calculates the amount of borax needed to raise your pool's pH by a specific amount based on your pool's volume.

3. Importance Of Proper pH Balance

Details: Maintaining proper pH balance (7.2-7.8) is crucial for swimmer comfort, equipment longevity, and effective chlorine performance. Low pH can cause eye irritation and damage pool surfaces, while high pH can reduce chlorine effectiveness and cause scaling.

4. Using The Calculator

Tips: Enter your pool volume in gallons and the desired pH increase. For best results, test your current pH level first and calculate the difference between current and target pH. Always add chemicals gradually and retest 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 too much borax in my pool?
A: Yes, excessive borax can raise pH too high and may lead to cloudy water or scaling. Always add chemicals gradually.

Q3: Is borax safe for all pool types?
A: Borax is generally safe for most pools, but consult your pool manufacturer's guidelines, especially for vinyl-lined pools.

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 ideal pH range for swimming pools?
A: The ideal range is 7.4-7.6, which is comfortable for eyes and optimal for chlorine effectiveness.
