Water Care

• High-purity powdered magnesium blend.
• 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 to form skeletal material.
• Stronger and more economical than liquid magnesium solutions; created for hobbyists  maintaining multiple reef aquaria.
• Formulated by a marine scientist.

Concentrated Magnesium Supplement for All Marine Fish & Reef Aquaria

• 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.

• High-purity powdered strontium.
• Incorporated by corals, clams, and other reef-building invertebrates into aragonite, themineral that is secreted as skeletal material.
• Stronger and more economical than liquid strontium solutions; created for hobbyists maintaining multiple reef aquaria.
• Formulated by a marine scientist.
• It is recommended that the strontium concentration in the aquarium be determined by using an accurate test kit prior to supplementing. Do not add this product directly to an aquarium containing live animals without first diluting in water as directed.
