Summer Smiles Spa Alka - 1 L Total Alkalinity Decreaser for Hot Tubs & Spas

Maintain balanced, comfortable hot tub water with Summer Smiles Spa Alka - 1 L, a liquid total alkalinity decreaser designed to help correct high alkalinity levels in hot tubs and spas.

Total alkalinity is an important part of spa water chemistry because it helps stabilize pH levels. When alkalinity becomes too high, pH can be difficult to adjust, potentially contributing to cloudy water, mineral scale buildup, and reduced water treatment efficiency.

Summer Smiles Spa Alka is designed to lower total alkalinity when testing indicates that levels are above the recommended range. Proper alkalinity control helps support stable water chemistry and makes routine spa maintenance easier.

Keeping total alkalinity within the appropriate range can also help reduce conditions that contribute to scale formation on spa surfaces, heaters, and other equipment.

The convenient 1 L liquid format makes Spa Alka a practical addition to your hot tub maintenance supplies, helping you manage water balance as part of your regular testing and treatment routine.

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 proper level helps:

• Keep spa water chemistry balanced

• Make pH adjustments easier to manage

• Reduce conditions that contribute to mineral scale

• Support consistent sanitizer effectiveness

• Help maintain clear, comfortable spa water

• Protect spa surfaces and equipment from water-balance problems

• Support a more predictable maintenance routine

Important: Lowering total alkalinity can also lower pH. Both measurements should be monitored carefully during treatment.
