pH Maintenance Guide for Hot Tubs & Swim Spas

Maintaining the ideal pH (7.2–7.8) ensures soft, clear, and balanced water while maximizing the benefits of Pure N Easy ionic sulfate minerals. Here's how to easily test, adjust, and stabilize your hot tub's pH levels check every couple months.

1. How to Test Your Hot Tub’s pH

Use pH test strips or a liquid test kit to check your water’s pH.

• Dip the strip in the water for a few seconds and compare the color to the chart.
• Ideal pH range: 7.2 – 7.8

2. How to Adjust pH Levels

If your pH is too high (above 7.8):

• Lower it with a pH reducer (e.g., sodium bisulfate or muriatic acid).

If your pH is too low (below 7.2):

• Raise it with a pH increaser (e.g., sodium carbonate/soda ash).
• Natural option: Add baking soda (sodium bicarbonate)—start with 1 tablespoon per 100 gallons, then retest.

Tip: Adjust in small increments and allow 30-60 minutes before retesting.

3. How Pure N Easy Keeps pH Stable with

Pure N Easy naturally helps keep your pH balanced by:

• Reducing the need for harsh chemicals that cause pH swings.
• Helping to buffer acidity & alkalinity, keeping pH stable over time.
• Preventing scale & corrosion, keeping water soft and equipment in good shape.

Best Practices for easy care

Rinse off lotions & oils before soaking—personal care products can alter pH.

• Keep filters clean — dirty filters can cause water imbalances.

4. Safe Oxidation Methods for Pure N Easy Users

While traditional chlorine and bromine are common oxidizers, there are safer and more natural alternatives for maintaining clear and healthy water with Pure N Easy. Consider these options:

• Food Grade Hydrogen Peroxide (H₂O₂): A gentle yet powerful oxidizer that helps break down organic matter without producing harsh byproduct .NO fillers Just pure H₂O₂
• Oxygen-Based Shock (Non-Chlorine Shock): Removes organic buildup while maintaining clear water without chlorine’s strong odor. Mostly fillers. Read the label.
• Epsom Salt in hot tubs? Not recommended in hot tubs but can be used in very small amounts. Epsom salt is a healthful addition to all water soaking. USP grade label directions include drinking as a laxative or watering plants. Usage in soak and bath tubs? Cups and cups, The sky's the limit.

5. Best Practices for Using Hydrogen Peroxide in Your Hot Tub/swim spa

Must be food grade not industrial

Food-grade hydrogen peroxide (3, 6, 12 or 35%) is a highly effective, chlorine-free oxidizer that works well with Pure N Easy. 3, 6, & 12 percent are room temp stable. 35 percent needs to be stored in freezer:

• Dosage: Add 2 ounces per 400 gallons of 35% / To match 2 oz of 35% food-grade hydrogen peroxide per 400 gallons, you would need:
• 24 oz of 3% hydrogen peroxide
• 12 oz of 6% hydrogen peroxide
• 6 oz of 12% hydrogen peroxide hydrogen peroxide per 400 gallons of water.
• after heavy use to keep water clear faster.

7. Final Tips for a Perfect Soaking Experience

• Use Hydrogen peroxide after heavy usage, due to the residual soaps, fabric softeners in clothes, hair spray, makeup, residual shampoo, etc.
• Skinny dip where appropriate preventing the need for oxidation agents. Hang and reuse suits. It is not uncommon to soak for 3-4 months or longer without adding an oxidizing agent as long as the water looks good, smells good, it is good to soak in.
• Adjust pH before adding new minerals or for best results.
• Add minerals to your water every 3-4-6 months to refresh your soaking experience.
