Chromium
Chromium (Cr) atomic number 24, 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. Chromium belongs in the transition metal group, along with molybdenum, vanadium, nickel, zinc, copper, iron, cobalt and ALL are naturally found in seawater. In reef aquariums, maintaining proper chromium levels is important for skeletal, biological, coral color, vitality and healthy coral growth, and supplementation will be necessary, especially in heavily stocked tanks.
Chromium Key Roles
Coral Skeleton Formation:
Chromium helps to stimulate skeletal formation.
Biological / Metabolism:
Chromium is essential for metabolic processes and enzyme production. It is used by zooxanthellae in photosynthesis. Chromium is required for conversion of nutrients, fatty acids and proteins to energy process for living things for growth , tissue repair, digestion, reproduction and must be maintained with all other within this group.
Chromium is metabolized by corals and by all organisms in the entire ecosystem including denitrification and conversion fatty acids to energy.
Enhanced Coral Coloration:
Chromium is used in the absorption of fatty acids enhancing vivid coloration and intensity of corals.
Aids in UV protection for corals and zooxanthellae.
Protection Against Parasites:
Chromium is part of the protective slime that corals excrete.
Chromium Levels
Natural Seawater Levels:
Chromium levels in natural seawater typically .00026 parts per million (ppm).
Target Aquarium Levels:
Many reef aquarists maintain chromium levels below this natural range.
PJS recommends aim for a chromium concentration of .0004-.0005 mg/L. This is a very small range!
Consumption Rate:
Fast.
Chromium Testing
ALWAYS test chromium levels in your reef aquarium before supplementing to determine if dosing is needed to avoid overdosing.
Testing:
Regularly test chromium levels using a reliable test kit or by sending water samples for ICP testing
Chromium Dosing
Start slowly by beginning with a low, gradual dose over days avoiding any sudden shifts in water chemistry and monitor the effects.
Methods:
Chromium can be dosed via liquid additives.
Consider Advanced Methods:
Dosing stock solutions with pumps and continuous drip systems can be used to maintain precise chromium levels.
Considerations
Avoid overdosing, as it can lead to imbalances and become toxic to corals and everything in your tank. LPS and SPS corals benefit from controlled levels of chromium. Chromium is essential for many metabolic processes and enzyme production. Chromium is used by all living organisms, aiding in a balanced eco system. Foods may contain levels of chromium that can influence your parameters. Dosing chromium, more is not the answer, time is the answer 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, coral bleaching.
