Yes. Taylor identifies R-0011L as calcium indicator liquid, used after R-0010 buffer and before R-0012 titrant.

Taylor instruction 5165 describes a red sample after adding the indicator when calcium hardness is present, followed by a red-to-blue change as R-0012 is titrated. Follow the complete procedure and interference guidance.

It is the indicator for the specified calcium-hardness procedure in pool and spa water. It does not measure salt concentration or replace the separate salt test.

Use the exact sample size, rinse the test tube before and after testing, hold reagent bottles vertically, and swirl as directed. Follow Taylor’s complete calcium-hardness procedure rather than combining steps from different kits.

Follow the bottle label and the current Taylor Safety Data Sheet for R-0011L. Keep the cap tightly closed and protect the reagent from direct sunlight; consult the SDS for the full handling and storage requirements.
