Magnesium Chloride Hexahydrate (Aquaculture Grade)
White crystals / flakes · CAS 7791-18-6
Also see our standard Magnesium Chloride Flakes page.
Overview
Magnesium Chloride Hexahydrate (Aquaculture Grade) is a high-purity magnesium salt used to correct magnesium levels in shrimp and fish ponds. Low-salinity and inland farms often lack magnesium, which affects moulting and growth; dosing magnesium chloride restores the balance. Suraj Chemicals supplies it from Chennai in 25/50 kg HDPE bags.
