• Contains no unwanted organic material such as EDTA, gluconate, or polygluconate
• Formulated by a marine scientist
• Basic Instructions: Shake product well before using. Add 5 ml (1 capful) of product per 20 US-gallons of aquarium water every other day or as needed to maintain the magnesium concentration within a range of 1,290 - 1,320 ppm. When used in this fashion, 250 ml treats up to 1,000 US-gallons (3,785 L).
