Item Description


NLCT Alka-Rise - Alkalinity Increaser

Quickly and easily increase your spa or hot tub`s water alkalinity level with Alka-Rise.

"Approved for all types of Spas and Hot Tubs including Wood" 



One of the tasks that spa and hot tub owners are faced with is controlling their spa`s chemical balance. Although it is not a difficult task, different locations use different water types which can pose problems for some spa owners. When the Total Alkalinity is reading low on a spa test, it is probably time to use an alkalinity increaser in your spa. 

Northern Light's Alka-Rise is specially formulated to work with all hot tubs and spas including use in any wooden hot tub. Maintaining your spas alkalinity level will prevent erratic changes in the pH levels of your spa`s water. Alka-Rise is compatible with all sanitizing methods, and will even help the Bromine or Chlorine in the spa work more effectively. 

Spa alkalinity increaser raises the total alkalinity of the hot tub water when it is low, which prevents the corrosion of your spa. Proper alkalinity levels are an essential part of spa/hot tub maintenance. Low total alkalinity causes the pH level to wander, and can lead to your spa`s chemicals causing discomfort to the skin and eyes. Test water levels regularly to ensure proper Alkalinity levels.

  • Alkalinity levels should be 102-125 ppm.

  • Prevents corrosion and equipment damage.

  • Reliable, safe and effective. Increase effectiveness of sanitization systems.
