Lithium

Lithium (Li) atomic number 3, PJS considers it to be a Minor element as it plays a crucial role in skeletal and tissue growth connection and development of corals and is used by all other reef organisms and is below 1ppm in seawater. In the industry it is considered a trace element, we need to fix that. Lithium belongs to the alkali metal group. Lithium is an essential minor element for a healthy reef aquarium, impacting everything and the overall reef health. It’s crucial to maintain lithium levels within the recommended range of .1–.25 mg/l (ppm).

Lithium Key Roles

Coral Skeleton Growth and Health:
A component for a strong skeletal structural calcification and tissue connection for hard corals and invertebrates exoskeletons.

Biological Processes:
Lithium is part of the metabolic process of corals and invertebrates in the production and strength of the skeleton and tissue connection by supporting the growth of both. Utilized by all marine life to support metabolic processes.

Protection Against Parasites:
Lithium is used by corals for a strong tissue and skeletal connection and formation aiding in defense to protect coral tissue from predators and parasites.

Lithium Levels

Natural Seawater Levels:
Lithium levels in natural seawater are typically .174 parts per million (ppm).

Target Aquarium Levels:
Many reef aquarists aim to maintain boron at natural seawater levels. PJS recommends aim for a lithium concentration of .2-.25 mg/L.

Consumption Rate:
Slow to moderate.

Lithium Testing

ALWAYS test Lithium levels in your reef aquarium before supplementing to determine if dosing is needed to avoid overdosing.

Testing:
Regularly test lithium levels using a reliable test kit or by sending water samples for ICP testing

Lithium Dosing

Start slowly by beginning with a low, gradual dose over many days avoiding any sudden shifts in water chemistry and monitor the effects.

Methods:
Lithium can be dosed via liquid additives.

Consider Advanced Methods:
Dosing stock solutions with pumps and continuous drip systems can be used to maintain precise lithium levels.

Considerations

Overdosing lithium can become toxic to reef inhabitants. Overdosing lithium will lead to undesirable algae overgrowth. Lithium is used by everything at every level, so its presence is essential and critical for overall reef health. Low lithium levels lead to coral bleaching, reduced tissue growth or loss, and week skeletal structure. Lithium is essential for skeletal and tissue formation. Lithium helps control the growth of certain algae that may have negative impacts to the reef environment. Lithium sources can be from improper RO/DI filtration, salts and leaching. All corals and invertebrates utilize lithium; it is steadily consumed. In corals lithium is used by both skeletal and biological processes in a symbiotic relationship. Lithium levels along with proper levels of calcium, magnesium, potassium, and alkalinity must be maintained. Lithium is essential for LPS and SPS coral growth and metabolisms.
