Description
  • Magnesium is present in natural sea water in a fairly high concentration (1350 – 1500 mg/L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants, algae and coral would not be able to survive.
  • Magnesium alsohelps to maintain the correct combination of calcium concentration and alkalinityas it slows down the formation of calcium carbonate which can absorb many important trace elements within the aquarium.

    • Maintaining acorrect magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growthby making it possible to maintain correct calcium and alkalinity figures.
