Brightwell’s MagnesION-P is part of a complete system for maintaining the major elements. The concentrated powder form is perfect for those who want to mix their own solutions at home for dosing by hand or with a dosing pump, and when coupled with Alkalin8.3-P and CalcION-P, it is convenient and economical to maintain stable levels of each of these critical components.

 

Overview

  • High-purity powdered magnesium blend for reef supplementation.
  • Provides magnesium, which helps regulate the balance between calcium and carbonates in aquarium water, and is a component of aragonite, the mineral secreted by reef-building organisms to form skeletal material.
  • Stronger and more economical than liquid magnesium solutions; created for hobbyists maintaining multiple reef aquaria.

 

Instructions and Guidelines

Basic
Dissolve 2.5 grams (~½ teaspoon) of product per 20 US-gallons of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed to maintain the magnesium concentration within a range of 1,290 - 1,320 ppm. When used in this fashion, 1,200 g treats up to 9,600 US-gallons (36,340 L).


Advanced
Create a stock solution by dissolving 20 grams (~4 teaspoons) of Magnesion-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase magnesium concentration (”[Mg2+]”) in 1 US-gallon (3.785 L) of water by 6.0 ppm. [Reference: Each g of Magnesion-P will increase the [Mg2+] in 1 US-gallon (3.785 L) of water by 114.4 ppm.] If initial [Mg2+] in the aquarium is below 1,288 ppm, add stock sol’n at maximum rate of 10 ml per 20 US-gallons daily until desired [Mg2+] is attained, then dose daily or weekly as needed (see below). Maintain [Mg2+] within a range of +/-10 ppm. Once desired [Mg2+] has been acquired, measure aquarium's [Mg2+] at the same time each day over a one- to two-week period to determine the daily rate of magnesium uptake (i.e. the decrease in magnesium). To determine daily dosing rate (preferable to weekly dosing): estimate volume of water in entire aquarium system (US-gal.); divide the daily decrease in [Mg2+] by 6.0; multiply this number by volume of water in system to obtain daily ml of stock sol’n required to maintain stable [Mg2+].



Caution
Keep out of reach of children. Not for human consumption.



Guaranteed Analysis

Technical Background

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. 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. 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. Once the balance between calcium and magnesium has been established, subsequent calcium supplementation yields immediate positive results. 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).
