Water Care

Highly-concentrated ionic potassium solution. Provides potassium, an important component of aragonite (the mineral secreted as skeletal material by corals and other reef-building marine organisms), complexed into pigments that enhance blue coloration of some small-polyp stony corals, important to proper neurological function, and depleted in marine aquaria by livestock.

• Highly-concentrated ionic strontium solution.
• Incorporated by corals, clams, and other reef-building invertebrates into aragonite, the mineral that is secreted as skeletal material.
• Stronger than most competing strontium solutions.
• Contains no unwanted organic material such as EDTA, gluconate, or polygluconate.
• Over 50% stronger than most competing products.
• Free of phosphate, silicate, and organic material.
• 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.

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.

• 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.

• * Highly-concentrated and stable iron solution for supplementing aquaria containing hermatypic organisms (i.e. “photosynthetic” or zooxanthellate corals, clams,      and their allies), macroalgae, coralline algae, mangroves, marsh grasses, and other desirable marine algae and plants.
• * Particularly suited to systems outfitted with a refugium or mud system.
• * Stronger than most competing products.
• * Composed of purified water and ultra-high purity materials.
• * Formulated by a marine scientist.

• Contains calcium, strontium, and magnesium in the same ionic ratios found in aragonite. This unique feature increases the usefulness of Kalk+2 to reef-building invertebrates such as corals, clams, calcareous algae, etc.
• Provides temporary alkalinity and helps maintain pH within the desired range when used as directed.
• Adds no conservative elements, such as chloride, to the aquarium.
• Improves upon the industry-standard powdered calcium supplement over the past three decades.
• Formulated by a marine scientist.

• Highly-effective alkalinity(KH)-increasing (”buffer”) solution.
• Helps increase pH stability in an aquarium by raising the alkalinity.
• Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
• Continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases.
• Over 50% stronger than most competing products.
• Free of phosphate, silicate, and organic material.
• Formulated by a marine scientist.
