Seachem Reef Advantage Magnesium 300g

Seachem Reef Advantage Magnesium is a concentrated optimized blend of magnesium, chloride, and sulfate salts. It is designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water. Severely depleted levels of magnesium can cause depressed pH levels and an inability to maintain proper calcium levels. Seachem Reef Advantage Magnesium does not contain any ammonia.

Directions for use:
BEGINNER: Use 5 g (1 level teaspoon) per 20 gallons twice a week. Dissolve in at least 250 mL (1 cup) of freshwater. ADVANCED: Check magnesium level, then follow addition regimen above until magnesium is adjusted to 1200–1350 mg/L. Each 5 g/80 L will raise magnesium by about 5 mg/L. Amount or frequency can be adjusted, but do not exceed 25 g/80 L per day. Thereafter, use as required to maintain magnesium. EXPERT: After determining the magnesium depletion rate, set up a continuous drip system. Use the following formula to determine how much to add to your top-off water: g=vm/80 (g=grams to add to top off water, v=volume of tank in liters, m=amount to raise magnesium in mg/L). For example, if you want to raise magnesium by 10 mg/L in a 200 liter tank, then you would add (200x10)/80=25 g into the top-off water. [For reference: 1 gallon=3.8 liters, 5 g=1 teaspoon]. HINTS: Use the Reef Status™ Magnesium, Carbonate & Borate to check magnesium levels.
