Coral Essentials Magnesium+Trace 2.75L

Description

Coral Essentials Magnesium+Trace 2.75L — Daily magnesium and potassium for the third part of a reef dosing routine

Calcium and alkalinity get the attention, but magnesium is the element that helps keep the other two in solution, and it falls slowly enough to be forgotten. Coral Essentials Magnesium+Trace 2.75L (SKU: CE-MAG275L) is the 2.75 L container of Coral Essentials’ Magnesium + Trace, a concentrated liquid magnesium at 12,500 ppm (mg/L) with the maker’s Coral Power Potassium blended in using its Coral Essentials Method. It completes the Brisbane company’s Primary Care trio alongside Calcium + Trace and Carbonate + Trace, and uses the same simple daily recipe so all three can run on one doser schedule.

That recipe is 3 mL per 100 L per day for a soft coral or LPS system, 6 mL for a mixed reef and 12 mL for an SPS-dominant tank. Coral Essentials states that 1 mL raises magnesium by 0.125 ppm in 100 L, so this is a maintenance dose to match daily use rather than a quick fix for a very low reading. The alternative method is to test magnesium regularly and set the dose from the measured depletion with the maker’s Primary Elements Dosing Calculator. Coral Essentials finds natural seawater levels right for most aquariums and 1,300 to 1,350 ppm desirable for high growth in SPS and hard coral systems. A 300 L mixed reef uses 18 mL a day, so this container lasts about five months.
