Contact Supplier
We Vinipul Inorganics Pvt Ltd are most trusted and reliable manufacturers, supplier and exporters of Magnesium Sulphate Heptahydrate. With our intelligence and more than 25 years of our expertise in this industry we have able to achieve tremendous growth in product of high quality and purity of Magnesium Sulphate Heptahydrate.
Magnesium sulfate heptahydrate is also used to maintain the magnesium concentration in marine aquaria which contain large amounts of stony corals, as it is slowly depleted in their calcification process. In a magnesium-deficient marine aquarium, calcium and alkalinity concentrations are very difficult to control because not enough magnesium is present to stabilize these ions in the saltwater and prevent their spontaneous precipitation into calcium carbonate.
