BIOKIT FRESH combines all the products needed to maintain a planted freshwater aquarium in the same-pack. BIODIGEST is made up of nitrifying bacterial strains that kick start biological filtration, which guarantees a clean and healthy aquarium. An optimal blend of over 15 heterotrophic strains is involved in the process. The different bacteria complement each other with each strain starting off a process continued by another strain, so that filters and the substrate are cleaned, the nitrate and phosphate rate is reduced and algae proliferation is therefore prevented. BIOTRACE provides the BIODIGEST bacteria with the micronutrients needed for their activity: trace elements, vitamins, amino acids, and natural plant surface active agents which facilitate absorption by the bacterial cells. The action of the aerobic, anaerobic and facultative strains is therefore optimized. BIOTRACE reduces the nitrate, phosphate and carbohydrate rates by increasing bacterial activity. The reduction in mulm, sludge and filamentous algae improves water quality. BIOVERT provides all the trace elements your plants need for strong and healthy growth, including directly bio-assimilable iron. BIVERT is nitrate and phosphate-free.
