Reagents for HI 783 (Magnesium) - 25 tests

Magnesium Checker In seawater, magnesium influences among other things the solubility of carbonates and calcium carbonate, which promotes indirect- ment the beneficial development of corals. The value of magnesium in the sea is around 1300 mg/L. In saltwater aquariums, a magnesium value between 1300 and 1350 mg/L is optimal. It is not wise to exceed these...

Magnesium Hardness Checker HC The hardness or hydrometric titer (TH) of water essentially corresponds to the presence of calcium and magnesium salts. It is directly linked to the geological nature of the terrain crossed. A calcareous soil will give hard water while a granite soil will produce rather soft water. The total hardness represents the sum of the calcium and...
