QFI Magnesium+ – 2500ml | S/M

Magnesium is an important element in sea water for hard and soft corals. A lack of magnesium is shown, among other things, by poor growth of calcareous red algae or very pale lime red algae. An addition of QFI Magnesium-Mix ensures coral growth, prevents color fading and intensifies coral colors. Important minerals are integrated with QFI Element Mix.
