Biotrace contains all the microelements needed for aquarium life(selected amino acids, enzymes, natural vitamins (including riboflavin)and a natural plant surface active agent enabling better membraneabsorption by cells).It also provides trace elements: sulphur for proteins, iron for plants andfish blood, cobalt for B vitamins and boron for many productsmetabolised during cell building, calcium, magnesium, manganese, zinc,molybdenum and potassium.Biotrace is a natural product that affects cellular bioactivators. Itdynamises the cellular metabolism of most of the bacteria living in freshwater aquariums and reinforces the biological reactions by increasingthe number of bacteria and therefore optimising water quality.Biotrace speedily accelerates the digestion of organic matter, reduces theBOD – biological oxygen demand – and therefore contributes to a raisedRedox potential. It also facilitates the elimination of nitrates andphosphates, which are an early warning sign of algae problems, andcarbohydrates, and therefore helps to regulate decomposition odoursand optimise water quality DOSAGE FOR EACHPRODUCT• Standard Range :1 vial for 200 l (50 US gal) /15 days• Pro Range :1 vial for 2 000 l (500 US gal) /15 days
