• Complete source of the elements and molecules that are directly used by corals, clams, and other reef-building invertebrates and organisms to create skeletal material and grow.
• Provides calcium (140,000 ppm), strontium, magnesium, and potassium in approximately the same ratios* in which they occur in aragonite.
• Very strong source of carbonates (derived from aragonite), the other important group of ions involved in aragonite formation.
• Increases alkalinity to help stabilize pH.
• Stronger than competing products.
• May be used as an inexpensive alternative to automated calcium reactor systems with similar results.
• Free of phosphate, silicate, and organic material.
• Formulated by a marine scientist

Determine the calcium concentration in the aquarium using an accurate test kit before supplementing.

Shake product well before using. Add 5 ml (1 capful) of product per 50 US-gallons of aquarium water every other day or as needed to maintain the calcium concentration within a range of 412 - 450 ppm. When used in this fashion, 250 ml treats up to 2,500 US-gallons (9,464 L). Liquid Reef may temporarily cloud aquarium water after addition, therefore it is recommended that the product be dosed at night.
