Instructions and Guidelines
Rinse material in freshwater or saltwater prior to initial placement in the aquarium system. Employ in a calcium reactor (main chamber or secondary chamber) at a total ratio of approximately 9:1 aragonite: NēoMag by volume. The rate of water flow through the reactor in conjunction with the pH of the water inside the chamber(s) will have the greatest impact on the rate of media dissolution. Follow the manufacturer’s instructions furnished with the calcium reactor to adjust the rates of water flow and CO2 injection and attain the desired concentrations of magnesium and calcium in the effluent. Measure alkalinity, calcium, and magnesium concentrations in the aquarium two- to four times each month during the course of using NēoMag to ensure that parameters are within the desired ranges, and make adjustments to the reactor system as required. As the biomass of corals and other reef-building organisms residing within an aquarium increase with time, so the demand of calcium, magnesium, and carbonates increases, as well; this being the case, the frequency at which aragonite and NēoMag must be replaced will increase.
Note that each reef aquarium has unique magnesium requirements and that it is possible for the magnesium demand in the aquarium to exceed the rate at which this element is liberated from the NēoMag material. Additionally, sea salt mixes are often deficient in magnesium, which puts the aquarist at an immediate disadvantage. In such cases, additional magnesium supplementation (such as with Brightwell Aquatics Magnesium or Magnesium-P) may be required to (re-)establish a natural seawater magnesium concentration (~1,290 - 1,320 ppm); once this concentration has been attained, NēoMag will generally maintain the concentration within the desired range when the reactor is efficiently operating. Another option is to employ a larger (or additional) calcium reactor to house a greater amount of NēoMag. Regardless of the method utilized, it is not recommended that the ratio of aragonite: NēoMag exceed 7:1 by volume, as this may increase the alkalinity of the aquarium beyond the desired level.
