For saltwater use only
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. 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. If calcium levels are found to be deficient, Seachem offers a variety of products that can be used to increase calcium: Reef Complete®, Reef Advantage Calcium™, Reef Calcium™, and Reef Kalkwasser™. Seachem also offers other reef specific test kits: Reef Status™: Strontium, Reef Status™: Magnesium, Carbonate & Borate Alkalinity and MultiTest™: Reef Special (tests for phosphate, silicate and iodide).
