SpaGuard/BioGuard Rapid-Dissolve Alkalinity Increaser 1" Tablets (1.25 lb): Easy Total Alkalinity Control
Quickly raise low total alkalinity (TA) levels in your hot tub with the genuine SpaGuard/BioGuard Rapid-Dissolve Alkalinity Increaser 1" Tablets. This 1.25 lb container of concentrated Sodium Bicarbonate tablets is a simple, pre-measured solution to a critical water balance issue. Maintaining proper total alkalinity (between 80–120 ppm) prevents rapid pH fluctuations (pH bounce) and protects spa equipment from damage and corrosion. The fast-dissolving tablets take the guesswork out of chemical dosing, ensuring stable, comfortable, and equipment-safe spa water with minimal effort.
Key Features
- Active Ingredient: Contains Sodium Bicarbonate.
- Raises Total Alkalinity: Effectively increases the total alkalinity (TA) level in your spa water to the ideal range (80-120 ppm).
- Prevents "pH Bounce": Stabilizes the water's pH level, preventing rapid fluctuations (pH bounce) which cause sanitizer inefficiency and equipment corrosion.
- Rapid Dissolve Formula: The tablets dissolve quickly and completely when placed in the filter compartment (with the pump running), leaving no residue.
- Protects Spa Equipment: Proper alkalinity prevents damage to heaters, pumps, and plumbing caused by unstable water chemistry.
- Convenient 1-Inch Tablets: The pre-measured tablet format makes dosing simple and eliminates the need for granular measuring.
- Enhances Bather Comfort: Ensures comfortable soaking conditions by keeping the water chemistry stable and balanced.
- Dosage Guide: Typically, 1 tablet per 250 gallons (1000 liters) raises total alkalinity by approximately 5 to 10 ppm.
