- Highly-concentrated ionic magnesium solution
- Provides magnesium, which helps regulate the balance between calcium and carbonates in aquarium water, and is a component of aragonite, the mineral secreted by reef-building organisms such as corals, clams, and their allies to form skeletal material. Stronger than most competing products
- 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, 4 liters treats up to 16,000 US-gallons.
