Nickel
Nickel Ni) atomic number 28, 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. Nickel belongs in the transition metal group, along with molybdenum, vanadium, zinc, copper, iron, cobalt and ALL are naturally found in seawater. In reef aquariums, maintaining proper nickel levels is important for skeletal, biological, coral color, vitality and healthy coral growth, and supplementation will be necessary, especially in heavily stocked tanks.
Nickel Key Roles
Coral Skeleton Formation:
Nickel helps to stimulate skeletal formation.
Biological / Metabolism:
Nickel is essential for metabolic processes and enzyme production. It is used by zooxanthellae in photosynthesis.
Nickel is metabolized at a cellular level by all organisms in the entire ecosystem including denitrification and conversion of inorganics to organics for consumption and export.
Enhanced Coral Coloration:
Nickel effects the reds while enhancing vivid coloration and intensity of corals.
Aids in UV protection for corals and zooxanthellae.
Protection Against Parasites:
Nickel in excess invites parasitic attacks.
Nickel Levels
Natural Seawater Levels:
Nickel levels in natural seawater typically .0007 parts per million (ppm).
Target Aquarium Levels:
Many reef aquarists maintain nickel levels below this natural range.
PJS recommends aim for a nickel concentration of .0004-.0005 mg/L. This is a very small range!
Consumption Rate:
Fast.
Nickel Testing
ALWAYS test nickel levels in your reef aquarium before supplementing to determine if dosing is needed to avoid overdosing.
Testing:
Regularly test nickel levels using a reliable test kit or by sending water samples for ICP testing
Nickel Dosing
Start slowly by beginning with a low, gradual dose over days avoiding any sudden shifts in water chemistry and monitor the effects.
Methods:
Nickel can be dosed via liquid additives.
Consider Advanced Methods:
Dosing stock solutions with pumps and continuous drip systems can be used to maintain precise nickel levels.
Considerations
Avoid overdosing, as it can lead to imbalances and become toxic to corals and everything in your tank. SPS corals benefit from controlled levels of nickel. Nickel is essential for many metabolic processes and enzyme production. Nickel is used by all living organisms, aiding in a balanced eco system. Nickel promotes polyp and tissue extension, but to much will do the opposite. Dosing nickel, more is not the answer, time is the answer Deficiency will lead to reduced growth and color vibrancy in corals, particularly reds. Overdosing will lead to tissue damage, coral bleaching. Deficiencies yield weak undefined colors with no contrast, grayish in color and slow growth.
