Iron concentrate (Eisen Konzentrat) will increase all colors but the most pronounced effect will be green color formation. A good indicator that your tank is iron deficient is red acroporas turning pale pink or green acroporas turning yellow.


Iron is excellent at bringing out many colors but green will be the most pronounced. However iron may also increase the density of zooxanthellae in coral which may result in coral darkening.


Careful dosing is required. Suggested dose is 1 mL per 50 gallons weekly. Do not exceed recommended dosing amount.


Darkening coral tissue indicates you may be overdosing. We recommend using yellow corals as good indicators, stop dosing when yellow corals display a green shimmer.
