The SOLENIS 86131 is a dry alkalinity increaser formulated to raise total alkalinity levels in spa and hot tub water. Maintaining proper total alkalinity is a foundational step in water chemistry management: it stabilizes pH, reduces the likelihood of pH swing, and protects both bathers and equipment surfaces. This product is a direct-dose granular treatment applied to spa water and is routinely handled by pool and spa service technicians as well as informed spa owners performing regular water maintenance.
This alkalinity increaser is suited for use in residential and light commercial spas and hot tubs. It is applied when total alkalinity readings fall below the recommended range, typically during routine water chemistry testing and balancing. Proper alkalinity control also reduces the risk of skin and eye irritation associated with unbalanced water, and helps prevent corrosion or scaling of spa surfaces and internal components.
Designed for use in residential and light commercial spas and hot tubs as a total alkalinity increaser for standard water balancing programs.
Water chemistry adjustments in spas should be performed by a qualified pool and spa service technician or a knowledgeable operator following product label directions. Always test current total alkalinity and pH levels before dosing. Add product to spa water with the circulation pump running to ensure even distribution, and retest water chemistry after the recommended wait period before allowing bather entry. Store product in a cool, dry location away from other pool chemicals.
