Water mold and bacteria may have collected in your garden hose and will contaminate the spa water. To prevent this, shut off nozzle end of your garden hose, place 1/2 tsp of Spa Chlorine Granules (99% sodium dichlor) down the spigot end of the hose, attach to the spigot and fill. Let sit for 5 minutes, then flush.
Fill spa. The Natural Hot Tub Company’s® garden hose Pre-Filter is highly recommended to help eliminate the need for additional chemicals. If you are on a well with hard metals, you can use water from you household water softener system if you have one.
Shock with 2 teaspoons of Spa Chlorine Granules (99% sodium dichlor) for hot tubs & spas up to 500 gallons. New hot tubs & spas are water tested at the factory and some still have this old water left in the lines. ‘Shocking’ the water the first day is recommended to resolve this issue.
After the temperature reaches 90 degrees or above, shake well and add The Natural Hot Tub Company® Water Treatment & Conditioner. (1/2-bottle for spas up to 250 gallons or 1-full bottle for spas up to 500 gallons.)
Run all pumps on high with all jets open for 5-minutes and enjoy. Check your water with a reliable test strip the next day, and only adjust if necessary.
