Seachem Reef Advantage Magnesium (600g)
*Treats 2400 gallons (9600L)
*Our Reef Advantage Magnesium is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water.
*Reef Advantage Magnesium contains no ammonia, which is a common contaminant in every liquid magnesium supplement on the market.
*Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser.
*USE: 1 level teaspoon (5g) per 20 gallons twice per week.
BETTER; Test for magnesium and add as needed to keep 1,200-1,350 mg/L
DO NOT OVERDOSE: As excess magnesium may enhance the loss of carbonate alkalinity.
