The strong and healthy growth promotes the production of cytokinins, which stimulate cell division and produce wider leaves and intense colours. Improves and maintains the biological balance in the aquarium. Does not contain nitrates or phosphates. Extremely economical to use. ProFito stimulates cell division, high concentrations of especially iron, potassium and magnesium in ProFito meet the plants' need for uptake of large amounts of these nutrients. The fertiliser also contains many other micro-nutrients (including manganese, boron, cobalt, lithium, molybdenum, copper, tin, nickel, fluorine, iodine, aluminium, zinc, selenium and vanadium). These substances, and a number of rare minerals, are added to give plants exactly what they need for trouble-free growth. Plants are stimulated to create cytokinins (plant hormones), which stimulate cell division. The leaves grow and become much wider and the colours become extremely vivid. Thanks to the optimal supply of nutrients provided by ProFito, plants grow faster and become stronger. As a result, undesirable substances such as certain nitrogen and phosphate compounds as well as nitrate, phosphate and ammonium are absorbed more quickly by the plants. ProFito "de-stresses" the water and a better biological balance is created in the aquarium. ProFito does not contain nitrate or phosphate. The nutrients in ProFito are retained in various ways by means of different chelators. Antioxidants and preservatives reduce ProFito's perishability, which means a longer shelf life. Cool and dark storage of the product also extends shelf life. Tips for use: the dosage is very economical: 10 ml per 100 l aquarium water every week. It is also possible to add 1/7 of the total dose daily. The colour of the product can vary from dark green to dark brown. The first few weeks 1/3 of the dosage is used. It can later be adapted to the best possible growth rate (weekly per 100 litres: 10 ml +/- 40%). The best dosage is determined by observing the youngest leaves on the plant. If they are light green, the dosage can be increased. Should algae appear and/or no further plant growth is observed, the dosage can be reduced. It may be good to introduce some fast-growing plants to the aquarium to avoid algae growth.
