Reef Status™ Calcium

  • 150 titration tests for calcium
  • Rapid & simple 3 step procedure
  • Sharpest color change endpoint
  • Precise results in 5 mg/L increments
  • Easy test validation with included reference

Natural sea water contains between 400 – 410 mg/L of calcium. A healthy reef environment should have between 380 – 420 mg/L of calcium. Levels above 420 mg/L are not beneficial. Levels below 380 mg/L should be corrected as soon as possible. This kit is capable of at least 150 calcium determinations and is designed specifically for seawater. The test is based on titration of calcium with EDTA in the presence of a calcium specific indicator dye after the coprecipitation of magnesium and strontium.

Reference Sample

It isn't necessary to run a reference test to use this kit; however, its proper performance can be validated by running a test in the normal manner except that the reference sample is used in place of aquarium sample. You might choose to run a reference test if you have cause to believe the test is giving incorrect results.

Titration Method

The test is based on titration of calcium with EDTA in the presence of a calcium specific indicator dye after the coprecipitation of magnesium and strontium. During the testing procedure, the sample transitions between pink and true blue. Once the sample turns blue, the test is complete. Calcium concentration corresponds to markings on the titration syringe.

Reef Status™ Calcium Kit Contents

  • Calcium Reagent 1
  • Calcium Reagent 2
  • Calcium Reference
  • Calcium Titrant
  • Sample Pipette
  • Sample Vial & Cap
  • Dilution Vial
  • Scoop
  • Titration Syringe

A: The syringe runs in reverse of dispensing, in other words, the more titrant that you dispense, the higher your calcium level. For example: If you use the entire syringe during titration, your calcium level is 500mg/L.

KEEP AWAY FROM CHILDREN! This kit is not a toy. It contains reagents that may be hazardous if used carelessly or contrary to instructions. Reagent #1 is a concentrated caustic, similar to a drain cleaner. The Titrant is a buffered chelating solution with antimicrobial preservatives. The Reference is a calcium chloride and magnesium sulfate solution. Do not get reagents in eyes, on hands, or clothing. Do not drink or swallow any reagents. If eye contact or swallowing occurs with Reagent #1 or the Titrant, seek medical attention. In case of discomfort or doubt, seek medical attention. Keep away from children.
