General Hot Tub and Spa Care - The Hot Tub Doctor

This is the standard for most hot tubs

Initial Fill Up of Hot Tub

(1) Mineral sequestering agent. Typically add 8 ounces per 500 gallons of water to remove minerals such as
iron, copper & manganese. Some city water systems do remove this prior to the water getting to your home.

(2) Test Alkalinity & ph using your test strips and adjust if necessary. Alkalinity should be between 80-120
parts per million (ppm). Alkalinity can be raised by simply adding baking soda as well as a Spa Up product.
The ph of water should be between 7.2 - 7.6 (FYI: ph = percent hydrogen). Adjust ph by using spa up/down if
necessary. Be certain to check this prior to adding any chemicals to your hot tub water. Some city water
supplies will have more chlorine in their water than the next town. When you are adding spa up/down do it
one ounce at a time, and allow at least 20 minutes for water to circulate before retesting and adding more.
Remember “less is best” when it comes to your hot tub.

(3) After testing the water you may add one teaspoon of granular chlorine or bromine to the water. Only if
needed.

Weekly Chemical Maintenance

(1) Test ph and Alkalinity levels and adjust if necessary.

(2) Add 1 tsp of chlorine/bromine

(3) Add 2 tbs of non-chlorine shock per 500 gallons of water.

(4) Add scale formation preventative, about 1 ounce per 500 gallons. Be sure to read directions on
manufacturers bottle for correct amount.

NOTE: Add chlorine/bromine & non-chlorine shock on different days for maximum
effectiveness and to reduce foaming.

*AN OZONE SYSTEM WILL NEGATIVELY AFFECT THE CHLORINE/BROMINE
READINGS. DO NOT ADD MORE THAN RECOMMENDED.
