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.

Maintenance Cycle – Every 2 Weeks:

BEFORE YOU BEGIN: To avoid unnecessary waste of useful chemicals be sure to clean cartridge filter, backwash sand filter or bump D.E. filter according to your filter’s pressure gauge reading.

For best results, you should wait 15 minutes between adding each chemical to the water. If possible add PristineExtra² at night and other chemicals the next morning. This prevents sunlight dissipation and increases the effectiveness of PristineExtra².

Step 1: Balance

1a. Test water balance parameters to ensure 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 water.

2b. Add 5 milliliters of PristineExtra² or PristinePower per 100 gallons of water as needed. Be sure to read product label instructions.

2c. Add 2 milliliters of PristineClear OR 2 milliliters of EnzyPure per 100 gallons of water.

Step 3: Add PristineBlue

3a. Test the PristineBlue level and add according to the Maintenance Dosage Chart below.

Filtration. Filtration is another vital part of keeping your spa water crystal clear. Most manufacturers recommend that water is circulated through the 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 volume, usage and bather load. Keep your filter in top shape by cleaning it regularly and replacing your cartridge as needed.

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

If possible, add PristineExtra² in the evening after the sunset and other chemicals the next morning. This prevents sunlight dissipation and increases the effectiveness of PristineExtra².

PristinePower can be used as needed for maintenance. It is used to oxidize organic materials that cause cloudy water. Follow label instructions.

You should always read the product label carefully for important warnings, dosage information and instructions.
