Why use AQUAFOREST Cobaltum Lab in a reef aquarium?
The cobalt (Co) is a trace element naturally present in seawater in very small quantities. It plays an important role in certain biological processes, notably as part of vitamin B12, which is essential to the metabolism of many organisms. It therefore indirectly contributes to the development of certain bacteria, microalgae and marine species that participate in the balance of the reef ecosystem.
AQUAFOREST Cobaltum Lab helps compensate for decreases in cobalt when these are confirmed by suitable analysis. Its concentrated liquid formula facilitates targeted corrections and its 200 ml format is suitable for reef aquariums requiring precise monitoring of trace elements.
The role of cobalt in the metabolism and coloration of marine fish
Cobalt is particularly known for its role in the structure of vitamin B12, also known as cobalamin. This vitamin is involved in various metabolic mechanisms and contributes to the functioning of many living organisms. In a marine aquarium, cobalt is therefore one of the trace elements associated with the biological activity of bacteria and certain beneficial algae.
According to AQUAFOREST, cobalt also contributes to the maintenance of the natural coloration of marine fish. However, its addition should not be considered a means of systematically intensifying colors. Appropriate supplementation is primarily intended to correct an insufficient concentration and preserve the aquarium's mineral balance.
What cobalt level should be maintained in a marine aquarium?
AQUAFOREST recommends a cobalt concentration between 0,0001 and 0,0006 mg/L (0,1 to 0,6 µg/L). These extremely low quantities require particular attention, as excessive dosing can quickly cause the recommended range to be exceeded.
An ICP analysis sensitive enough to measure trace levels of cobalt makes it possible to check its concentration and determine whether supplementation is necessary. It is important to take into account the laboratory's detection and quantification limits, especially when results are close to measurable thresholds.
Dosage of AQUAFOREST Cobaltum Lab 200 ml
The dosage depends on the aquarium's actual water volume and the desired increase in cobalt. The concentrated solution allows targeted corrections to be made:
- 1 ml of Cobaltum Lab increases cobalt by 0,001 mg/L (1 µg/L) in 100 liters of water.
- Recommended concentration: between 0,0001 and 0,0006 mg/L (0,1 to 0,6 µg/L).
- Maximum daily dose: 1 ml per 100 liters of water.
Warning: a dose of 1 ml per 100 liters increases cobalt by 1 µg/L, which is above the upper limit of the recommended range if the initial concentration is zero. It is therefore essential to accurately calculate the required amount before each addition. For small adjustments, prior dilution may facilitate the administration of very small quantities. The maximum daily dose is a limit to be observed, not an amount to be added systematically.
Supplementation should be based on the results of ICP analyses and adapted to the aquarium's actual consumption. When several additions are necessary, they should be spread over several days to avoid an excessive increase in concentration.
Directions for use and precautions for AQUAFOREST Cobaltum Lab
AQUAFOREST Cobaltum Lab can be added gradually to a well-circulated area of the aquarium or to the sump to ensure good distribution. For small quantities, the use of precise dosing equipment is recommended. A suitable dosing pump can also facilitate additions when cobalt consumption has been clearly determined.
Cobalt must be supplemented with caution due to the extremely low recommended concentrations. An excess of this trace element can be harmful to marine organisms. Regular analyses make it possible to monitor its progression and adjust additions only when necessary. The product is intended exclusively for aquarium maintenance and must be kept out of reach of children.
