Add 5 ml (1 capful) of product per 20 US-gallons of aquarium water every other day or as needed to maintain the magnesium concentration within a range of 1,290 - 1,320 ppm. We develop formulae for aquaria based on empirical data, using observation and measurement rather than theory.īasic: Shake product well before using. It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements be used to establish natural seawater parameters in the reef aquarium, providing a stable ionic foundation on which to build.Īll Brightwell Aquatics liquid water care supplements are made with purified water and high purity materials. Once the rate of magnesium uptake in the aquarium has been determined, the proper dosing rate of this product can be easily calculated. The rate at which magnesium is extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other conditions therefore, each aquarium will have different requirements for the rate of magnesium supplementation. Keeping magnesium within a range of 1,290-1,320 ppm will maintain the desired balance, and provides enough of the element to reef-building organisms for the formation of aragonite (~0.10% Mg by weight). Once the balance between calcium and magnesium has been established, subsequent calcium supplementation yields immediate positive results. No matter how much calcium is added, its natural seawater concentration of 412 ppm will never be sustained until the magnesium concentration begins to approach 1,290 ppm.
In the absence of adequate magnesium ions, calcium and carbonate ions bond rapidly, depleting their concentrations in the system and creating the false impression that heavier supplementation is required to re-establish the desired concentrations. Magnesium plays a vital role in reef aquaria: it helps maintain calcium and carbonate (composing the majority of measurable alkalinity) concentrations by limiting unwanted inorganic precipitation with each other. Contains no unwanted organic material such as EDTA, gluconate, or polygluconate.
Secreted by reef-building organisms such as corals, clams, and their allies to
Provides magnesium, which helps regulate the balance between calcium andĬarbonates in aquarium water, and is a component of aragonite, the mineral.Highly-concentrated ionic magnesium solution.
