Product Description ------------------- Seachem Reef Advantage Magnesium 1.2Kg Ingredients ----------- magnesium sule, sodium chloride P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Directions ---------- Beginner Use 5 g (1 level teaspoon) per 80 L (20 gallons) twice a week. Dissolve in at least 250 mL (1 cup) of freshwater. For precise dosing, use the Seachem Digital Spoon Scale. Advanced Check magnesium level (use Reef Status Magnesium to test magnesium levels), then follow addition regimen above until magnesium is adjusted to 1,200–1,350 mg/L. Each 5 g/80 L will raise magnesium by about 5 mg/L. A 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 (or skip the math and use our Dosage Calculator) 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=a 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]. Notes: Use the Reef Status: Magnesium, Carbonate & Borate test kit 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. Water Volume Units US Gallons Liters Current Mg mg/L (ppm) Desired Mg mg/L (ppm) To reach your desired level use g ( tspn) Do not exceed 25 g/80 L (20 US gallons) per day Considerations Use to test magnesium levels We recommend a magnesium level between 1200-1350 mg/L. Make large adjustments slowly to avoid overshooting intended level. A or frequency can be adjusted, but do not exceed 25 g/80 L per day. Dissolve in at least one cup of freshwater. Excess magnesium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. DO NOT OVERDOSE Do not exceed 25 g/80 L (20 US gallons) per day. Excess magnesium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement.
