Calcium can be found in many freshwater sources and this any amount present in the water used at the C1 phase can cause false high readings. In addition, many hobby grade reverse osmosis deionized water systems may not adequately remove calcium. This can vary based on the types of filters used, their effectiveness and frequency of replacement. We recommend using deionized water with low conductivity or pure vapor distilled water commonly found in most pharmacies.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan\u003eNever use tap water to clean your cuvettes. This is especially important for the HI758U Marine Calcium Checker as calcium is commonly present in tap water and residual amounts present in the cuvette will elevate results produced by the Checker. Our HI98703-50 Cuvette Cleaning Solution ensures the glass cuvette used for colorimetric measurements remains clean and free from imperfections.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan\u003eCalcium Checker Troubleshooting Tips\u003c\/span\u003e\u003c\/p\u003e\n\n\u003col\u003e\n\n\u003cli\u003e\u003cspan\u003eNever rinse your cuvettes with tap water or saltwater\u003c\/span\u003e\u003c\/li\u003e\n\n\u003cli\u003e\u003cspan\u003eUse pure vapor distilled water from your local pharmacy at C1 phase.
