Iron is one of the most important minor trace elements in reef aquariums, especially for corals and sea anemones. It greatly increases the respiration capabilities of algae, helping to increase the photosynthesis potential of plants and corals. Iron will also enhance green coloration in stony corals. It is recommended to maintain iron levels in reef aquariums at 0,006– 0,012 mg/l (ppm). Iron can be used with: SPS corals LPS Corals Soft Corals Clams & other filter feeders Caution: Overdosing may cause negative effects. Instructions: Shake well before use. Add 1 drop of Iron per 100 L (27 gal) daily. 1 ml of Iron (~15 drops) in 100 l (27 US gal) raises the iron level in water by 0.005 ppm (5 μg/l).
