Water Care

• The calcium-bearing component of a two-part method for dosing calcium and carbonates (the substances largely responsible for increasing alkalinity (”buffering capacity”)) in the same ratio as that found in natural seawater.
• Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
• Simplifies calcium and alkalinity maintenance; economical for particularly large systems.
• Contains no phosphate, silicate, or organic material.
• Formulated by a marine scientist.

• The calcium-bearing component of a two-part method for dosing calcium and carbonates (the substances largely responsible for increasing alkalinity
• (”buffering capacity”)) in the same ratio as that found in natural seawater.
• Ionically-balanced with respect to natural seawater concentrations of calcium and carbonates when used in equal amounts with Reef Cōde B.
• Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
• Simplifies calcium and alkalinity maintenance.
• Stronger than most competing products.
• Contains no phosphate, silicate, or organic material.
• Formulated by a marine scientist.

• High-purity powdered calcium.
• Increases the concentration of calcium in marine aquarium water to provide corals and  other reef-building invertebrates with one of the most important elements required for growth.
• Stronger and more economical than liquid calcium solutions; created for hobbyists maintaining multiple reef aquaria.
• Formulated by a marine scientist.
• It is recommended that the calcium 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.

• Highly-concentrated ionic calcium solution.
• Increases the concentration of calcium in marine aquarium water to provide corals and other reef-building invertebrates with one of the most important elements required for growth.
• Is ionic rather than chelated, and 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.

• The alkalinity-bearing component of a two-part method for dosing calcium and carbonates (the substances largely responsible for increasing alkalinity (”buffering capacity”)) in the same ratio as that found in natural seawater.
• Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
• Simplifies calcium and alkalinity maintenance; economical for particularly large systems.
• Contains no phosphate, silicate, or organic material.
• Formulated by a marine scientist.

• The carbonate-bearing component of a two-part method for dosing calcium and carbonates (the substances largely responsible for increasing alkalinity
  (”buffering capacity”)) in the same ratio as that found in natural seawater.
• Ionically-balanced with respect to natural seawater concentrations of calcium and carbonates when used in equal amounts with Reef Cōde A.
• Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
• Simplifies calcium and alkalinity maintenance.
• Stronger than most competing products.
• Contains no phosphate, silicate, or organic material.
• Formulated by a marine scientist.

Sizes: 250ml, 500ml, 2L, 20L

• Highly-effective alkalinity-increasing (”buffer”) powdered blend. 
• Helps increase pH stability in an aquarium by raising the alkalinity; continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases. 
• Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material. 
• Formulated by a marine scientist. 

Determine alkalinity in aquarium with an accurate test kit prior to supplementing. Do not add this product directly to an aquarium without first diluting in water as directed.

• 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.

• 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.
