Seachem Reef Advantage Magnesium 300g
	DIRECTIONS: BEGINNER: Use 1 level teaspoon per 80 L (20 gallons*) twice a week. Dissolve in at least one cup of freshwater. ADVANCED: Check magnesium level, then follow dosing regimen above until magnesium is adjusted to 1200–1350 mg/L. Each dose will raise magnesium by about 5 mg/L. Size or frequency of dose can be adjusted, but do not exceed 25 mg/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: t=0.01vm (t=teaspoons to add to top off water, v=volume of tank in gallons*, m=amount to raise magnesium in mg/L). For example, if you want to raise magnesium by 10 mg/L in a 50 gallon* tank, then you would add 0.01x50x10=5 teaspoons into the top-off water. HINTS: Use the Reef Status:™ Magnesium, Carbonate & Borate to check magnesium levels. DO NOT OVERDOSE: Excess magnesium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if magnesium & carbonate additives are added on alternate days or at least 30 minutes apart. Slight clumping of this product may be encountered but does not impact its use; any clumps will break up very easily.
