Supplement contains concentrated nickel. Nickel is necessary for functioning almost all microorganisms. Its deficiency results in depleted metabolism of nitrogen and iron.

1 ml of the product increases the nickel level by 0.001 mg/l (ppm) in 100 litres (27 US gal) of water.

Recommended level of nickel in aquarium water is 0.001 – 0.01 mg/l (ppm). Dosage should be based on microelements consumption. Note, that each aquarium is different and final dosage depends on the coral cast and individual aquarium needs.
Both, deficiency and excess micronutrients will affect aquarium inhabitants, therefore dosage should be selected and modified on the basis of regular Aquaforest Lab water tests.
