Brightwell Aquatics NeoNitro is a ready mixed solution to increase the nitrate level in the marine aquarium, to enable the natural phosphorus uptake in reef tanks with inadequate nitrate content, as in ultra-low nutrient reef tanks.Lowering ammonia, nitrite, and phosphate concentrations without the use of chemical filtration media and without resorting to polluting the system with organic material to raise the nitrogen content.Recommended for use by advanced reef aquarists maintaining ultra-low nutrient content systems.May be used with MICROBACTER7, REEF BIOFUEL and/or KATALYST, and NeoPhos to achieve desired nutrient content in reef aquaria for improved health and colouration of inhabitants.1ml NeoPhos will increase the phosphate concentration in 3.8 liter by ~ 0.25ppm.As macroalgae will consume much more nitrate than phosphate it is for an optimal macroalgae growth recommended to maintain a ratio between nitrate & phosphate in the marine aquarium / planted reef tank between 20:1 to 100:1.Which means that when you have for example a nitrate concentration of 2 ppm the phosphate level should be 0,02 ppm.It is as well recommended to keep for an optimal macroalgae growth a nitrate level of at least 2 ppm and a minimum phosphate level of 0.02 ppm, as otherwise the macroalgae may starve and potentially die off.CautionKeep out of reach from children, not for human consumption.
