Manganese
Manganese (Mn) atomic number 25, PJS considers it to be a Trace element as it plays a crucial role in the biological and metabolic process in corals and is used by all reef organisms and is measured by ppt in seawater. Manganese belongs in the transition metal group, along with molybdenum, nickel, zinc, copper, iron, cobalt and ALL are naturally found in seawater, maintaining proper manganese levels is important for biological processes, coral color, vitality and healthy coral growth, and supplementation will be necessary, especially in heavily stocked tanks.
Manganese Key Roles
Photosynthesis / Zooxanthellae:
Utilized by enzymes that detoxify harmful oxygen radicals produced during photosynthesis for corals.
Utilized by zooxanthellae for photosynthesis to harvest the energy from light
Biological / Metabolism:
Manganese is essential for metabolic processes and enzyme production. It is used by zooxanthellae in chlorophyl production for photosynthesis. Manganese is required for conversion and production of nutrients and proteins to process for living things for growth , tissue repair, digestion, reproduction and must be maintained with all other within this group.
Manganese is metabolized by corals and by all organisms in the entire ecosystem including denitrification and pigment production.
Enhanced Coral Coloration:
Manganese promotes reds as well as enhancing vivid coloration and intensity of corals.
Aids in UV protection for corals and zooxanthellae.
Protection Against Parasites:
Manganese supports the overall health, promoting resistance to parasites.
Manganese Levels
Natural Seawater Levels:
Manganese levels in natural seawater typically .002 mg/L or 2 parts per billion (ppb).
Target Aquarium Levels:
Many reef aquarists maintain manganese levels below this natural range.
PJS recommends aim for a manganese concentration of .00025-.0003 mg/L. This is a very small range!
Consumption Rate:
Fast.
Manganese Testing
ALWAYS test manganese levels in your reef aquarium before supplementing to determine if dosing is needed to avoid overdosing.
Testing:
Regularly test manganese levels using a reliable test kit or by sending water samples for ICP testing
Manganese Dosing
Start slowly by beginning with a low, gradual dose over days avoiding any sudden shifts in water chemistry and monitor the effects.
Methods:
Manganese can be dosed via liquid additives.
Consider Advanced Methods:
Dosing stock solutions with pumps and continuous drip systems can be used to maintain precise manganese levels.
Considerations
Avoid overdosing, as it can lead to imbalances and become toxic to corals and everything in your tank. Overdosing will cause corals to darken and algal blooms, including cyano outbreaks. Manganese is essential for many metabolic processes and enzyme production. Manganese is used by all living organisms, aiding in a balanced eco system. Manganese is highly recommended for high PAR lighting. Manganese has high antioxidant properties helping corals resist stress from high temperatures. Manganese has a high rate of precipitation. Foods may contain levels of manganese that can influence your parameters. Dosing manganese, more is not the answer, time is the answer. Manganese is essential for some corals proper care, such as Gonipora. Dosing manganese can influence consumption of iodine, iron, calcium and many other elements. Deficiency will lead to reduced and improper growth, sensitivity to lights, imped the ability to produce or consume nutrients, impacting the symbiotic relationship of corals and zooxanthellae. Overdosing will lead to tissue damage, tissue detachment and coral bleaching.
