Cobalt plays a key role in zooxanthellae photosynthesis and the structure of coral tissue . When it is deficient, corals tend to lose their luster , their growth slows, and the tissue becomes thinner and more fragile. In fish, a deficiency can impact vitality, as cobalt is involved in the production of vitamin B12 , which is essential for the formation of red blood cells.
There are many causes of deficiency: a synthetic salt base that's too poor, aggressive filtration (with activated carbon or ozonation), or simply a lack of supplementation. With ATI Labs Cobalt, there's no more guesswork. This concentrate allows you to precisely correct the deviations detected by your ICP test.
Here are the instructions for adjusting your cobalt intake:
| Aquarium volume | Desired increase | Recommended dosage |
|---|---|---|
| 100 L | +4 µg/l | 1 ml |
| 100 L | +0.4 µg/l | 0.1 ml (max/day) |
Each bottle contains 60,000 µg of cobalt . Never exceed the recommended daily dose to avoid unnecessary stress on your ecosystem.
