JBL MagnesiuMarin is a magnesium supplement for marine aquaria. Use JBL MagnesiuMarin to aid in the production and maintenance of the calcareous skeletons and hard shells of calciferous red algae, hard and soft corals and invertebrates in your reef aquarium. These animals include rock corals, soft corals, sponges, sea urchins, crustaceans, bivalves and gastropods. 50 ml of JBL MagnesiuMarin in 50 l water will increase the magnesium content by 50 mg/l. We also suggest that you use this product in conjunction with JBL CalciuMarin.
