Proper control of magnesium level is imperative for the health and growth of corals and many other invertebrates. Continuum recommends that you maintain a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm). Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L).

  • Reef Basis Magnesium is a high purity magnesium in dry form, designed to safely raise the magnesium level in marine aquariums, providing essential magnesium for invertebrate growth and to regulate the balance between calcium and carbonates.
  • Contains no acetate, EDTA, polygluconates.
  • Made from anhydrous salts, not hydrated salts.
