SeaKlear Spa Alkalinity Up - 2 Pounds

SeaKlear Alkalinity Up raises total alkalinity (TA) in hot tub water. Maintaining proper alkalinity levels improves your hot tub sanitizer’s effectiveness while also preventing scale build up. It also helps prevent the corrosion of metal elements, hot tub surfaces, eliminates pH “bounce,” and keeps pH level.

Active ingredients:

  • 100% - Sodium hydrogen carbonate 


  • Add 1 oz. Alkalinity Up to hot tub water
  • Allow water to circulate for 30 min with system on
  • Retest water, repeat steps until desired level is reached

Note: The desired range for TA is between 80 and 140 ppm.
