Step 1: Remove and clean cartridge filter with ecoone® Filter Cleanser.

Step 2: Use existing water to deep-cleanse your spa.
Do this for 1 to 24 hours using approximately 4oz. of ecoone® Fast Acting Spa Cleanser. New spas should be filled and cleansed before starting ecoONE as manufacturer ‘wet testing’ may cause buildup of mold, or other contaminants. NOTE: When switching from a biguanide product, drain and refill spa before cleansing and replace cartridge filter.

Step 3: Clean spa shell and cover. Use ecoone® Shell and Liner Cleaner. Drain spa and rinse surfaces with fresh water. Refill and drain spa 2 to 3 times to assure removal of all contaminants from plumbing. NOTE: Never use household cleaners to clean your spa - they can damage the shell and cause foaming.

Step 4: Adjust pH, alkalinity, calcium hardness. Only do if neccessary. Refill spa and heat to operating temperature. (pH Range: 7.2 – 8.2, Alkalinity: 80 - 120, Hardness: 200+) NOTE: If you have hard or well water, initial water issues can be solved by filling your spa using ecoone® Spa Pre-Filter.

Step 5: Add Sanitizer. Add minimum recommended amount of sanitizer or one dissolving packet of ecoone® Shock (per 250 gallons.)

Step 6: Add ecoone® Monthly to spa with jets and blowers running. 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.

CLEAN YOUR FILTERS: ecoone's products rely heavily on filtration. Regular and prober cleaning of the spa's filters using a product such as ecoone Pre-Filter are pivotal to the success of using the product

MAINTAIN WATER LEVEL: Water should be at least 7 1/2 centimeters (3 inches) above filter intake. Low water levels will lead to cloudy water.

AVOID DETERGENTS: Bathing suits and clothing will retain detergent left over from laundering. Detergent will dissolve in the water and create foam. To prevent this, wash bathing attire in water without any detergent to ensure it is free of it.

INCREASE CIRCULATION: Too little circulation may lead to water quality issues.



SHOWER FIRST: Showering will reduce the introduction of dirt, oils, hair products, deodorants, makeup, perfume etc. to the spa.

KEEP THE AIR ON: ecoone works better with air in the water. Leave the air intakes "open" between uses to maximize ecoone's effects. It is better if you can point the jets upwards to increase water agitation when you are not in the spa.
