Why Keeping the pH in Your Hot Tub Balanced Is So Important
There’s nothing quite like slipping into a warm, bubbling hot tub after a long day. But to keep that experience enjoyable—and safe—it’s crucial to keep the water’s chemistry in check, especially its pH level.
What Is pH and Why Does It Matter?
pH measures how acidic or basic (alkaline) your hot tub water is on a scale from 0 to 14. Ideally, your hot tub’s pH should stay between 7.2 and 7.8, which is slightly basic and perfect for bathers and your equipment.
Here’s why it matters:
1. Comfort for Your Skin and Eyes
Most People believe if there eyes are burning its because of the chlorine, which is not the case. When the pH is too high or too low, you’ll feel it—literally. Unbalanced pH can lead to itchy skin, burning eyes, and irritated nasal passages. If your hot tub makes you feel worse instead of relaxed, chances are your pH is off.
2. Protects Your Hot Tub Equipment
Unbalanced pH can corrode metal parts like heaters, jets, and pumps or cause scale buildup on surfaces and in plumbing. This can lead to expensive repairs and reduced lifespan of your hot tub components.
Low pH (acidic water) eats away at metal and rubber.
High pH (alkaline water) causes scaling and cloudy water.
Neither is good.
3. Boosts Sanitizer Effectiveness
Your sanitizer (like chlorine or bromine) works best in water that’s in the proper pH range. If the pH is too high, your sanitizer becomes much less effective—meaning bacteria and algae can thrive, even if your chemical levels look normal.
4. Prevents Cloudy or Foamy Water
Imbalanced pH often causes cloudy, foamy, or discolored water—not exactly inviting. Proper pH helps maintain clear, sparkling water that looks as clean as it feels.
5. Saves You Money in the Long Run
Neglecting pH balance can lead to:
Increased chemical usage
Higher energy bills (due to clogged heaters or scale buildup)
Costly damage to pumps, filters, and plumbing
Balancing your pH regularly helps you avoid major maintenance costs and keep your hot tub running efficiently.
How to Keep pH in Balance
Test your water 2–3 times per week using test strips or a digital tester.
Use pH increasers Like this or pH decreasers Like this to adjust levels as needed.
Keep total alkalinity in check (80–120 ppm) to stabilize pH.
Final Thoughts
Your hot tub is a place to unwind—not stress over skin rashes, weird smells, or expensive repairs. By maintaining a balanced pH, you’ll enjoy safer, clearer water, longer-lasting equipment, and better peace of mind.
So next time you dip in, take a moment to check your pH—it’s one of the simplest and smartest things you can do for your hot tub (and yourself).
