Determine calcium, magnesium in water samples for aquarium and aquaculture. The water sample can be brackish water and seawater with the salinity higher than 5 ppt. It is designed to be compact size and allow to measure 120 times. The test can be performed simply, quickly and easily. This titration test kit first carry out the calcium test (0 – 800 ppm), which has a sharp color change, going from pink to blue when reach the calcium level in the sample. Then follow by the magnesium test (0 – 1725 ppm) which also has a significant color change, going from orange to green, when reach the magnesium level in the sample.

Easy to use, accurate, fast test, economic. Can measure 120 tests. Ca range from 0 – 800 part per million (ppm) with the resolution of 40 ppm per drop. Mg range from 0 – 1725 ppm with the resolution of 50 ppm per drop. For freshwater and marine aquarium and aquaculture, pond water, ground water, drinking water. Test calcium (Ca) and magnesium (Mg) level in water. Suitable for brackish water and seawater with the salinity higher than 5 part per thousand (ppt).
