This granular chlorine product immediately disinfects water, keeping it clean and clear. Additionally, Chlor-Aid will not disturb the pH or alkalinity balance in your water.
SpaBoss Spa Shock (2 lb.) is the shock product that you need to keep contaminants from ruining your hot tub water and plumbing.
