- 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.
