Brightwell Aquatics

Overview

  • High-purity powdered magnesium blend.
  • 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.
