Brightwell Aquatics Hydrat-MG - Hydrated Magnesium Salt Solution for Use in Marine Aquarium, 2-L

In some instances, marine and reef aquarists may find it beneficial to maintain the magnesium concentration in their aquaria within a range of 1,500-1,800 ppm for prolonged periods of time. The period of time will vary between systems and is completely dependant upon the magnesium concentration that is maintained, as well as the extent to which maintaining the magnesium at an elevated concentration is associated with obtaining the desired results. Additionally, evidence suggests that the specific magnesium salts utilized are important to obtaining the desired results. Hydrat-Mg is a concentrated magnesium solution that makes use of these specific, hydrated (not anhydrous) magnesium salts, in proper ionic ratios. Brightwell Aquatics Magnesion and Magnesion-P are composed of anhydrous magnesium salts, which offer greater purity than hydrated salts; Magnesion is also more concentrated than Hydrat-Mg. Regardless, the conditions that would dictate that the magnesium concentration in a reef system be maintained within a range of 1,500-1,800 ppm are, in most cases, more rapidly addressed with Hydrat-Mg than with magnesium supplements composed of anhydrous salts. Choosing to maintain an elevated [Mg2+] for an extended period of time assumes that the aquarist understands the impacts and potential risks that doing so can have on a marine aquarium.
