Hot Tub pH Balance Is Not a Vibe Check

We get it. You dipped a toe in, it felt warm, and you figured everything was fine. But pH doesn’t care how chill you feel. It’s not a suggestion. It’s a number. And if it’s off, your hot tub becomes a cauldron of potential issues.

Low pH? That’s acidic water eating away at your equipment and stinging your skin. High pH? That’s scale buildup, cloudy water, and a filter begging for mercy. Neither is cute.

What pH should actually be

Your pH should live between 7.2 and 7.8. That’s the spa sweet spot. When it’s in that range, your sanitizer works better, your skin feels better, and your hot tub doesn’t rebel.

How pH goes off the rails

• Using the wrong chemicals
• Too many bathers in too little water
• Neglecting alkalinity like it’s optional (it’s not)

The fix is simple

Test your water. Adjust with a pH increaser or decreaser. Don’t just top off the chlorine and call it a day. Balanced water makes everything work better. And no, your skin isn’t “just sensitive.” It’s reacting to chaos.

Give your spa what it actually needs. Not what vibes right.
