Spa Chemical Dosage Chart

Keeping your water properly balanced and sanitized begins with knowing the correct gallonage of your spa. The chart below answers that question. When calculating the amount of product to add, remember that getting the exact dosage is not critical because repeating an application is sometimes required. Just as important, remember to check your water regularly for a safe, clean soak every time.

1. Locate your spa from the chart to the left and round the gallonage to the nearest 100. Always round up if you are uncertain. (Gallonage has fluctuated a little over time as spa designs changed, but not enough to affect proper dosages.

2. When calculating dosages, remember that 1 ounce = 2 tablespoons.

3. Use that old tablespoon from the kitchen that does not match anything else, and dedicate it to spa care. Rinse after each application, and keep it from the kids and animals.
