JBL MagnesiuMarin 500ml

"Magnesium supplement for marine aquariums • Indispensable for the care of corals and calciferous red algae. • Content can be monitored with JBL Test Set Ca/Mg 500 ml. Product description The popular calciferous red algae and invertebrates which develop a calcarous skeleton or a hard shell in reef aquariums need sufficient magnesium to build up their shells or skeletons. These animals include rock corals, soft corals, sponges, sea urchins, crustaceans, bivalves, gastropods, etc. Dosage A capful (50 ml) increases the magnesium content in 50 l water by 50 mg/l Add the required amount to the aquarium in an area with good water movement. Possible consequences of inadequate magnesium content: Defective growth in rock corals and calciferous red algae Insufficient skeletal development in echinoderms and moulting problems in crustacea Tip: The equally important calcium content can be adjusted to the required level of 400 - 440 mg/l using JBL CalciuMarin.
