Summer Smiles Spa Alka+ - 750 g Total Alkalinity Increaser for Hot Tubs & Spas

Keep your hot tub water balanced and comfortable with Summer Smiles Spa Alka+ - 750 g, a total alkalinity increaser designed to help maintain proper water chemistry in hot tubs and spas.

Total alkalinity plays an important role in spa water maintenance by helping stabilize pH levels and preventing sudden fluctuations. When alkalinity is too low, pH can become difficult to control, potentially leading to corrosive water conditions and unnecessary wear on spa components.

Summer Smiles Spa Alka+ is formulated to raise total alkalinity when testing indicates levels are below the recommended range. Maintaining appropriate alkalinity helps support stable pH, effective water treatment, and a more consistent soaking experience.

Regular testing and adjustment of total alkalinity can also help protect your spa investment by reducing the risk of water-balance problems affecting heaters, plumbing, and other equipment.

The convenient 750 g container is a practical addition to your hot tub maintenance supplies, making it easy to keep an alkalinity increaser on hand whenever water adjustments are needed.

Available at Splash Pool & Spa in Peterborough, Ontario, proudly serving Peterborough, the Kawarthas, and spa owners across Canada.

Why Total Alkalinity Matters

Total alkalinity measures the water's ability to resist changes in pH. Maintaining the correct level helps:

• Stabilize pH levels and reduce sudden fluctuations

• Reduce the risk of corrosive water conditions

• Support proper spa water balance

• Make routine pH adjustments more predictable

• Help protect spa heaters, plumbing, and equipment

• Support consistent sanitizer performance

• Maintain comfortable, well-balanced spa water

Important: Total alkalinity and pH are different measurements. Increasing alkalinity may also affect pH, so both should be tested and adjusted as needed.
