{"product_id":"salifert-calcium-test-50-100t","title":"Salifert Calcium Test 50-100T","description":"\u003cp\u003eCalcium is a major constituent of coralline algae, the skeletal material of hard corals and the skeletal needles of soft\/leather corals. In many cases too low a calcium concentration retards coral and coralline algae growth.\u003c\/p\u003e\u003cp\u003eCalcium also fulfills many important biological functions. In a healthy aquarium, the growth and multiplication of corals, calcareous algae and other organisms can result in calcium depletion\u003c\/p\u003e\u003cp\u003eTo maintain a stable environment it is important that the calcium content should not fluctuate by more than 15 mg\/L from the optimum range of 420 - 450 mg\/L so regular testing should be carried out. This means that any calcium test used should have an accuracy of significantly less than 15mg\/L otherwise it will be difficult to monitor such fluctuations.\u003c\/p\u003e\u003cp\u003eThe Salifert test kit measures in steps of 5 mg\/L and has an accuracy of 10 mg\/L. The color change is precise, detecting small but significant fluctuations in the concentration of calcium. The test is not affected by magnesium. Sufficient for 50-100 tests. Can be used for marine water, freshwater and garden pond water\u003c\/p\u003e","brand":"Salifert","offers":[{"title":"Default Title","offer_id":57054418731339,"sku":"SAL-CALCIUM","price":13.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7065\/4027\/files\/6_6_662010_38.jpg?v=1776422449","url":"https:\/\/krakencorals.co.uk\/products\/salifert-calcium-test-50-100t","provider":"Kraken Corals","version":"1.0","type":"link"}
