1.If using a pH balancing product, like Ph Balance, add the entire bottle to the spa water. Run the spa on high speed (jets) for 15 minutes, then proceed with Step # 2. If you are not using a pH balancing product, go directly to Step # 2.
2.Add 2 bottle caps of concentrated Demineralizer or Metal Out to the water. Some brands require that you must add the entire bottle. Read the instructions on your bottle to be sure.
3.Add 2 bottle caps of Spa Shock  to the water. Do not use Non-Chlorine Spa Shock the first time when refilling tub with fresh water.
4.Add 2 bottle caps of Water Clarifier to the water. (Do not use clarifier if using pH balancing products)
5.Add 2 ounces of enzyme based oil-eating product to the water. (Optional)
6.Test and adjust the pH of the water to 7.6 – 8.2 by adding either pH Plus or pH Minus (Don’t do this if using  a pH balancing product).
7.Test and adjust the Alkalinity of the water to between 100 – 120 by adding Alkalinity Plus (Don’t do this if using a pH balancing product.).
8.Add 4 – 6 Bromine Tablets to the Bromine Floater and put the floater in the spa water.
9.Run spa on low speed (heat) for at least 6 hours to heat up, properly mix all the chemicals and completely filter the water.

1.Test water for Bromine, pH and Alkalinity.
2.Add 4 – 6 new Bromine Tablets to the  Floater if necessary. Try to maintain an average Bromine level of between 1.0 – 1.5.
3.Adjust the Alkalinity to between 100 – 120 and the pH to 7.6 – 8.2 (Don’t manually adjust the pH or Alkalinity if using a pH balancing product).
4.Rinse off the cartridge filter with fresh water.
5.Squeeze out Scumballs or Scumbugs and rinse them off with fresh water.
6.Add 2 bottle caps of Water Clarifier. (Do not use Clarifier if using Perfect pH)
7.Add 2 bottle caps of Spa Shock, Spa Chlor or Non-Chlorine Spa Shock.
8.Add 2 ounces of Scumdigester or any other enzyme based oil-eating product to the water. (Optional)
9.Clean water line and lip of spa with Spray Away  (do not use a soap based cleaner !)

Daily Operation

1.Spa water should filter on low speed for at least 3 hours per day.
2.Bromine Floater should have Bromine Tablets in it and should remain in the spa at all times, except when you are using it.
3.Scumballs or Scumbugs should remain in spa at all times, except when you are using it. They absorb surface oils and reduce “ring around the spa” at the water line.
4.Ozonator (if equipped) should operate on low speed at least 3 hours for every 12 hours. If using an Ozonator, you should also use at least 2 – 3 Bromine Tablets in a Bromine Floater as well.
