Keep your spa or hot tub water perfectly balanced with Clear Spa Alkalinity 2 lbs CSTA002, a targeted formula that elevates total alkalinity into the ideal 80 to 150 ppm range. When alkalinity drops too low, pH becomes erratic and can swing wildly, potentially corroding equipment and degrading water quality. This fast-dissolving, fully soluble treatment restores pH stability quickly, allowing your sanitizers to work at peak efficiency and simplifying your overall spa care routine.

Key Benefits

• Raises Total Alkalinity: Purpose-built to bring total alkalinity up to the optimal 80-150 ppm window, creating a balanced and comfortable spa environment.
• Prevents pH Fluctuations: Anchors pH levels in place, eliminating the corrosive swings that damage heaters, jets, and other spa components while compromising water clarity.
• Fast-Acting and 100% Soluble: Dissolves rapidly and completely upon application, delivering near-instant correction with no undissolved residue left behind.
• Enhances Sanitizer Effectiveness: Stable alkalinity lets chlorine, bromine, and other sanitizers perform at their best, resulting in cleaner and more inviting spa water.

Usage Directions

Review all label instructions before application: Apply according to all precautionary statements and usage guidelines. When your spa or hot tub pH bounces rapidly between low and high readings, requiring repeated additions of soda ash or acid, low total alkalinity is typically the underlying cause. This condition may stem from a naturally soft water source or from chemical reactions between existing alkaline compounds and other spa treatments. Either way, correction is straightforward: apply this product as needed to hold total alkalinity between 80 - 150 parts per million (ppm).

Symptom: Low total alkalinity - leads to unstable, drifting pH in spa water. Remedy: Apply Clear Spa 104 Alkalinity until total alkalinity reaches the 100-150 ppm target range.
