Product Description

SpaGuard/BioGuard Rapid-Dissolve pH Decreaser 1" Tablets (1.25 lb): Quick & Easy pH/Alkalinity Control 

Quickly and safely lower high pH and total alkalinity levels in your hot tub with SpaGuard/BioGuard Rapid-Dissolve pH Decreaser 1" Tablets. This 1.25 lb container of concentrated sodium bisulfate tablets provides a simple, pre-measured solution to water balance issues, which are vital for swimmer comfort and equipment longevity. Maintaining a pH level between 7.2 and 7.6 helps prevent skin and eye irritation, protects spa equipment from corrosion and scaling, and ensures your sanitizer works efficiently. The fast-dissolving tablets are much safer and easier to handle than liquid acids and take the guesswork out of chemical dosing. 

Key Features

  • Active Ingredient: Contains 96.9% Sodium Bisulfate.
  • Rapid Dissolve Formula: The tablets dissolve quickly in the filter compartment with the pump running, leaving no residue behind.
  • Lowers pH & Alkalinity: Effectively decreases both high pH and total alkalinity to recommended levels (pH 7.2-7.6).
  • Protects Spa Equipment: Prevents scale formation and corrosion on internal components like heaters, pumps, and surfaces caused by improper water balance.
  • Enhances Bather Comfort: Balancing the water chemistry prevents skin and eye irritation, ensuring a more comfortable soaking experience.
  • Convenient 1-Inch Tablets: The pre-measured tablet format makes dosing simple and eliminates the need for granular measuring.
  • Dosage Guide: Typically, 1 tablet per 250 gallons (1000 liters) lowers the pH by approximately 0.1 to 0.2 units.
