Aqua Medic NO3 reduct contains organic compounds that serve bacteria as an additional carbon source and thus stimulate greater reproduction. These bacteria are used by corals as food or are skimmed off. Previously absorbed nutrients disappear with them, so that the nitrate and phosphate content of the water gradually decreases. The corals use the bacteria as additional food that leads to an improvement in colour and polyp extension.Aqua Medic NO3 reduct+ mixture of organic carbon sources to reduce nitrate and phosphate+ including dosing measure for easy use+ improves coral growth+ improves polyp extension and colour+ prevents undesired algae growth, by nutrient controlDosage Aqua Medic NO3 reductAdd 2 ml Aqua Medic NO3 reduct per 100 litres of aquarium water, per day
