Pool Chemical Calculator
Use for the Sustain® 3-Part System
1. To estimate how much of each chemical you will need, the first step is to determine the volume of your pool. The following form represents an easy method to calculate pool volume.

Rectangular Pools:
Length x Width x Average Depth x 7.5 = Total Gallons

Round Pools:
Length x Width x Average Depth x 5.9 = Total Gallons

Oval Pools:
Length x Width x Average Depth x 6.7 = Total Gallons
2. The second step is to enter the number of weeks you will be running your pool in the box below to determine the estimated amount of each Sustain System Product your pool requires for one season.
3. Estimated Seasonal Requirements
Sustain Summer Shield Chlorine Extender | Sustain 3” Chlorinating Tablets | Sustain 3/4” Shield Energizing Tablets |
---|---|---|
After determining your pool's product requirements, check the Sustain product labels for the proper application of Sustain Summer Shield Chlorine Extender and Sustain Tablets. If you need additional information ask your Authorized Sustain System Dealer.
The results shown above are based upon Axiall Water Treatment Product’s best estimate for usage of these products. Your consumption of chemicals may vary, increasing or decreasing based upon a number of environmental factors such as rain, temperature, and wind-swept debris like leaves, fertilizers, etc. Regular heavy bather loads can also affect consumption.
