Hot Tub Start Up

Whether you’re filling your tub up for the first time, or if you’re just refilling from a scheduled drain and clean, following these steps will help ensure that your tub is chemically balanced and ready to go. These steps are made to follow if your hot tub is equipped with the CleanZone Ultra Sanitation System. Additional steps or changes in steps may be necessary if your tub does not have the CleanZone Ultra unit installed. REMEMBER: While adding chemicals it is always better to add too little of a product because you cannot remove the product once it is added.


1.)    Sanitizer, choose one of the following:

a.       Amerse Chlorine Granules or

b.       Leisure Time Bromine Granules or

c.       Natural Chemistry Bromine Tablets

2.)    Amerse Calcium Increaser

3.)    Amerse Metal and Stain Control

4.)    Amerse pH & Alkalinity Increaser

5.)    Amerse pH & Alkalinity Decreaser

6.)    Amerse Foam Eliminator

7.)    Amerse Clarifier

8.)    Leisure Time Renew Oxidizer

9.)    Insta-Test 4 Test Strips


1.)    Fill your hot tub up with your garden hose. Remove the filters and place the hose directly in the filter housing. This will help prevent an airlocked pump. An air lock is the restriction or stoppage of water flow caused by air being trapped in the pipe system. An airlock will prevent the pump from operating.

a.       Depending on the water quality in your area, you may need to use a pre-filter. Bring in a water sample to determine if a pre-filter is needed.

b.       Well water mineral levels may vary. Bring in a water sample to determine what extra steps may be necessary to get started.

2.)    Mix 1 bottle of the Amerse Metal & Stain Control into at least 1 gallon of hot tub water and dilute. With jets on high, pour this solution into the hot tub. This removes excess magnesium and iron that causes bodies of water to turn cloudy and green.

3.)    Under the settings menu and check to make sure the time is set correctly. This will ensure that your filtration times are accurately running while the tub is not in use.

4.)    Set the filtration time. You’ll want to set the filtration to run at least 2 hours in the morning and at least 3 hours in the evening or after use. Filtration should run while the tub is not in use.

5.)    Set the temperature to the desired range. “Low” will have a maximum temperature of 99 degrees Fahrenheit. “High” will have a maximum temperature of 104 degrees Fahrenheit.

6.)    When you’re tub reaches at least 85 degrees, you’re ready to begin chemically balancing your water.


When adding chemicals into the tub, dilute them first in at least 1 gallon of water directly from the hot tub. When solution is fully diluted, pour into the hot tub with jets on high. Chemical granules that are allowed to settle at the bottom of the tub will damage and stain the acrylic.

1.)    Remove one test strip from the Insta-Test 4 Test Strip container and dip into your hot tub water. Remove and read immediately, basing the color off the range provided on the side of the tube. Each test strip reading is valid for up to 30 seconds after dipping the strip in water.

2.)    Your Calcium level should be between 150 to 200 ppm. While the jets are still on add ½ oz. of Amerse Calcium Increaser to increase the hardness level 7 ppm. Continue to add until you reach the optimum Calcium Hardness level.

3.)    Test the pH and alkalinity range. Your pH should be between 7.2 and 7.8. Alkalinity should be between 80 to 120 ppm.

a.        If the pH and Alkalinity level is too high, above 7.8 and above 120 ppm, add ¼ oz or 1 ½ teaspoons of Amerse pH & Alkalinity Down. Let jets run for 30 minutes and test with test strip again. Repeat the process if the pH and Alkalinity continues to be too high.

b.        If the pH level is too low, below 7.2 and below 80 ppm, add 1 oz or 2 tablespoons of pH and Alkalinity Up. Let jets run for 2 hours and retest with test strip again. If the pH and Alkalinity level continues to test too low, repeat the process.

c.       Note: If your pH level is within the optimum range and your Alkalinity level is still low, you can use a separate product that will raise the Alkalinity level alone.

4.)    Test your sanitation levels. You should have chosen to either use Chlorine or Bromine. You should never use more than one type of sanitation chemical in your system. Chlorine levels should be 1 to 3 ppm. Bromine levels should be 3 to 5 ppm.

a.       Chlorine Granules: Add 2 tablespoons of Amerse Chlorine Granules. Let run for 15 to 20 minutes and test. Repeat until residual chlorine remains at 1 to 3 ppm. For maintenance, add 2 teaspoons after each use, and 1 additional teaspoon for each additional user.

b.       Bromine Granules: Add 2 tablespoons of Leisure Time Brominating Granules. Let run for 15 to 20 minutes and test. Repeat until residual bromine levels remains at 3 to 5 ppm. For maintenance, add 2 teaspoons after each use and 1 additional teaspoon for each additional user.

c.       Bromine Tablets: Fill tab feeder with Natural Chemistry Bromine Tablets. Open feeder to show 1 window per 100 gallons. Let sit for 24 to 48 hours. Test to ensure residual levels of bromine is within the optimum range of 3 to 5 ppm.  You may use the hot tub within the 24 to 48 hour window.
