Calcion
Brightwell Aquatics Calcion
Concentrated Calcium Supplement for all Marine Fish & Reef Aquaria
- 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.
Calcium is one of the most prevalent ions in seawater, and is required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies.
In seawater, calcium is present at a concentration of approximately 412 ppm; in reef aquaria, maintaining calcium within a range of 412 - 450 ppm will enable corals and other reef-building invertebrates to grow rapidly when all other physical and chemical requirements are met.[Magnesium, strontium, and carbonate ions are also complexed into aragonite, and their importance in a reef aquarium cannot be overstated.]
The rate at which calcium is extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of calcium supplementation. Once the rate of calcium uptake in the aquarium has been determined , the proper dosing rate of this product can be easily calculated.
It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements be used to establish natural seawater parameters in the reef aquarium, providing a stable ionic foundation on which to build.
250 ml treats up to 9,464 Litres

Calcion-P
Brightwell Aquatics Calcion-P
Calcium Supplement in Powder Form for all Marine Fish & Reef Aquaria
- 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.

Kalk+2
Brightwell Aquatics Kalk+2 : a unique Kalkwasser
Calcium, Strontium, and Magnesium Supplement for all Marine Fish & Reef Aquaria
- 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.
Calcium, magnesium, and strontium are required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies.
Brightwell Aquatics Kalk+2 provides these elements and may also be used to help regulate pH in reef aquaria.
Kalk+2 does not contain chloride salts, which is a strong point for some hobbyists.
The use of kalkwasser-type products remains very popular with many seasoned hobbyists, regardless of innovations in calcium-delivery methods
Kalk+2 is intended for use by experienced hobbyists who are familiar with kalkwasser (calcium hydroxide-based) products.
The calcium concentration (”[Ca2+]”) and pH in the aquarium should be determined by using an accurate test kit prior to supplementing.
Do not add this product directly to an aquarium without diluting in water as directed, and do not overdose; it must be added in a controlled fashion with a dosing device

Reef Code A
Brightwell Aquatics Reef Code A : Calcium
Balanced Calcium & Alkalinity System for all Marine Fish & Reef Aquaria
Calcium Element of a two part system
- 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 Côde 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.
This method of calcium and carbonate supplementation is advantageous to hobbyists interested in a simple and effective means of providing the very elements and molecules required for growth of reef-building organisms such as corals, clams, and their allies.
Corals and other reef-building organisms require adequate and stable available calcium and alkalinity if they are to thrive, regardless of how perfect the remainder of their environment is.
Under most conditions, the mineral that is secreted as skeletal material is known as Aragonite, composed mostly of carbonate and calcium by weight. Reef-building organisms must extract these substances from the surrounding water in order to secrete new skeletal material for growth. By maintaining the same ratio of calcium ions and carbonates in an aquarium as that found in natural seawater, these organisms have the necessary building blocks available in the proper proportions, even if the hobbyist chooses to maintain higher concentrations of these substances.
For maximum effectiveness of the Reef Côde method, the magnesium concentration in reef aquaria should be adjusted to, and maintained between, 1,290 - 1,320 ppm before using these products (alone or together) or any other calcium and alkalinity products. Doing so helps prevent unwanted precipitation between calcium and carbonate ions.
The rate at which calcium and carbonates are extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other conditions; therefore, each aquarium will have different requirements for the rate of supplementation.
Once the rate of calcium uptake in the aquarium has been determined, the proper dosing rate of this product can be easily calculated.
250 ml treats up to 4,732 Litres
When used in equal amounts with Reef Côde B, the calcium and carbonates being added are in the same ratio found in natural seawater
