Pro Tip
Always store the test strip vial tightly sealed in a cool, dry location and avoid reaching inside with damp fingers, as moisture inside the bottle degrades the reagent pads quickly.
Common Questions & Instructions
How do I get the most accurate reading with Sirona test strips?
Turn off spa jets and immerse the strip to a depth of 6 inches for 2 seconds. Remove it with the pads facing up, do not shake off excess water, and compare against the color chart immediately to read your pH, total alkalinity, and sanitizer levels.
Can I use these strips if my spa uses bromine instead of chlorine?
Yes. Sirona test strips are designed for full compatibility with both chlorine and bromine sanitizing systems, alongside monitoring calcium hardness up to 400 ppm.
How often should I test hot tub water and replace test strips?
We recommend testing your spa 2 to 3 times per week or before each use. A standard bottle typically covers 2 to 3 months of regular testing, and strips should be replaced once depleted or after reaching their printed expiration date.
