Our EcoOne basic kit includes all the basics. Use with your choice of sanitizer.

Add minimum recommended amount of sanitizer or one dissolving packet of ONEShock™ (where available) per 250 gallons (950 liters)
With jets and blowers running, add full bottle of EcoOne® monthly to spa. For heavily used spas, we recommend adding ½ to 1 cap full of ecoONE® Enzyme Active Filter Booster to the filter compartment after each filter cleaning.
