Calcium Reef Status Test Kit - Seachem

Features

• 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

Overview

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.

At Insidereef, we use the Callium Reef Status as a reliable backup to our advanced spin disc testing equipment. While spin discs provide quick and comprehensive results, having a second opinion is essential if something seems off. This additional layer of testing helps us catch any discrepancies and ensure the stability of our marine aquariums, keeping water parameters in check and our fish thriving.

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.
