Red Sea Reef Foundation C 1kg — Magnesium powder for the Reef Care Program
Powder is the economical way to buy magnesium for a reef, since a kilogram of salts makes more stock solution than any bottle holds. Red Sea Reef Foundation C Magnesium Powder 1kg (SKU: RED304) is the powdered magnesium supplement in Red Sea’s Reef Foundation series, blended salts of magnesium forming the C part of the Foundation A, B and C system in the Reef Care Program. Red Sea states that 1 g raises the magnesium level of 100 L by 1.34 ppm, and that 1 kg makes 1.7 L of stock solution. Dosing follows the magnesium the aquarium is measured to consume rather than a fixed daily amount.
Red Sea’s Reef Care Program recipes set magnesium between about 1,220 and 1,390 ppm by aquarium type, 1,350 ppm for a mixed reef, with 1,310 ppm the level in Red Sea Salt at 35 ppt. A 1 kg tub can raise a 400 L aquarium by about 335 ppm in total, or hold it steady for a long time against a typical weekly draw. The powder is dissolved before dosing, as a daily addition or as stock for a dosing pump, and Red Sea advises testing all three foundation elements weekly on daily dosing, adjusting each with its own A, B or C supplement.
Usage & Application
When to Use
- Reef Care Program users: The magnesium half of a Foundation A, B and C regime.
- Larger reefs: Systems whose weekly magnesium draw makes bottled liquid an expensive habit.
- Making stock solution: Filling a doser reservoir from powder at 1 kg per 1.7 L.
- Lifting a low reading: Gram-by-gram correction up to the recipe level for the tank type.
Dosing & Administration Guide
- Test magnesium: Compare the reading with the Reef Care Program recipe for the tank.
- Calculate: 1 g per 100 L raises magnesium by 1.34 ppm; weigh the grams for the change wanted.
- Dissolve and dose: Mix into water before adding, or make stock for a dosing pump.
- Retest: Weekly if dosing daily, monthly if dosing weekly; trim A, B and C individually.
