Tropic Marin Elimi-NP is a liquid carbon dosing concentrate for nutrient reduction for advanced reef aquarists. The nutrient conditions for the lower animals in the reef aquarium (corals, sponges, and others) are ideal, if nitrate and phosphate are present in the lowest concentrations. Tropic Marin Elimi-NP is concentrated organic carbon for the effective and efficient reduction of nitrate and phosphate in reef aquariums through the introduction of these compounds into additional biomass. Tropic Marin Elimi-NP is suitable for all saltwater aquariums with increased phosphate concentration and a low nitrate-phosphate ratio, as frequently observed in reef aquariums with a calcium reactor.Tropic Marin Elimi-NP+ efficient reduction of nitrate and phosphate in the reef aquarium+ designed specifically for reef aquariums with coral calcium reactor, but is suitable for all aquariums with an increased concentration of phosphate and a low nitrate / phosphate ratio+ suitable for an aquarium stocke
