Spa, Hot Tub and Swim Spa Maintenance

Calculating Water Volume:

One of the most important pieces of information you can have for your spa, hot tub or swim spa is the water volume in gallons. Whether you’re adjusting pH, shocking or adding PristineBlue, accurate water volume is essential to proper dosage. Using too much or too little can cause a problem to develop or get worse!

Ideally, your water should be metered as the spa is filled to obtain an accurate volume. Since metering is rarely considered, we’ve provided basic formulas for calculating volumes for various spa configurations.

RECTANGLE OR SQUARE SPA To determine your water volume in a rectangular or square spa, multiply length x width x average depth in feet to calculate cubic feet. Then multiply cubic feet x 7.5 to determine gallons of water.

ROUND OR OVAL SPA To determine your water volume in a round or oval spa, multiply radius times radius x 3.14 x average depth x 7.5. The radius is half the diameter or the distance from edge to center of the spa.

IRREGULAR If you have an irregular spa shape or are having difficulty calculating your water volume, see your dealer or contact the manufacturer of your spa, hot tub or swim spa.

For Spa or Hot Tub

Maintenance Cycle – Every 2 Weeks:

BEFORE YOU BEGIN: To avoid unnecessary waste of useful chemicals, ALWAYS clean your filter PRIOR to performing maintenance steps.

Step 1: Balance

1a. Test water balance parameters to insure they are in recommended ranges.

1b. Add chemicals, if necessary, to balance water to appropriate ranges below:

  • Total Alkalinity: 50 to 90 ppm
  • pH: 7.2 to 7.6
  • Calcium Hardness: 100 to 400 ppm
Step 2: Prep

2a. Add 1 milliliter of PristineClean per 100 gallons of spa water.

2B. Add 5 milliliters of PristineExtra per 100 gallons of spa water.

Step 3: Add PristineBlue

3a. Test the PristinBlue level

3b. Add appropriate milliliters of PristineBlue according to Maintenance Dosage Chart below

REMINDER: PristineMist on spa cover as needed to prevent odor and discoloration.

Filtration. Filtration is another vital part of keeping your spa water crystal clear. Most spa manufacturers recommend that water is circulated through the spa filter a minimum of 6 to 8 hours a day, but you can’t filter too much. Be certain that your filtering schedule is adequate for your spa volume, usage and bather load. Keep your filter in top shape by cleaning it regularly and replace your cartridge as needed.

IMPORTANT: DO NOT ADD PristineBlue more often than 2 week maintenance cycles.
