Hot Tub Things® pH & Alkalinity Up – Premium Water Balance Solution

Why Proper pH & Alkalinity Matter

Maintaining the right pH level (7.2-7.8) and total alkalinity (80-120 ppm) is crucial for hot tub water quality. Low pH makes water acidic, which can corrode metal components, etch plaster surfaces, and cause uncomfortable burning sensations. Low alkalinity leads to pH instability, making it difficult to maintain balanced water chemistry. Our pH & Alkalinity Up solution addresses both issues effectively.

• Active Ingredient: Sodium Bicarbonate (Baking Soda) or Sodium Carbonate (Soda Ash) depending on formulation
• Form: Granular
• Solubility: Fast-dissolving
• Storage: Store in a cool, dry place away from other chemicals
• Shelf Life: Indefinite when stored properly

How to Use pH & Alkalinity Up

Step 1: Test your water using test strips or a digital tester to determine current pH and alkalinity levels.

Step 2: Calculate the required amount based on your spa's water volume and current readings. Generally, 1 tablespoon raises pH by approximately 0.1 in 500 gallons of water.

Step 3: With the spa jets running, sprinkle the product directly into the water, distributing it around the perimeter.

Step 4: Allow the jets to circulate for 15-20 minutes, then retest and adjust if necessary.

Pro Tip: Always adjust alkalinity first, then pH, for best results and more stable water chemistry.
