Supplement contains concentrated chromium. It’s a natural compound of a seawater. In a closed aquarium system it is quickly consumed by marine organisms, so it should be regularly supplemented. In order to keep steady parameters, the concentration of cobalt should be systematically monitored.
1 ml of the product increases the chromium level by 0.0005 mg/l (ppm) in 100 litres (27 US gal) of water.
Recommended level of chromium in aquarium water is 0.0001 – 0.0004 mg/l (ppm).
Please remember, that maximum safe daily dose is 1 ml per 100 litres of water. If you need a higher dose, split it into a few days.
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.
