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

Magnesion
Brightwell Aquatics Magnesion
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
Magnesium plays a vital role in reef aquaria: it helps maintain calcium and carbonate (composing the majority of measurable alkalinity) concentrations by limiting unwanted inorganic precipitation with each other.
In the absence of adequate magnesium ions, calcium and carbonate ions bond rapidly, depleting their concentrations in the system and creating the false impression that heavier supplementation is required to re-establish the desired concentrations.
No matter how much calcium is added, its natural seawater concentration of 412 ppm will never be sustained until the magnesium concentration begins to approach 1,290 ppm. Once the balance between calcium and magnesium has been established, subsequent calcium supplementation yields immediate positive results. Keeping magnesium within a range of 1,290-1,320 ppm will maintain the desired balance, and provides enough of the element to reef-building organisms for the formation of aragonite (~0.10% Mg by weight).
The rate at which magnesium is 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 magnesium supplementation. Once the rate of magnesium 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.
All Brightwell Aquatics liquid water care supplements are made with purified water and high purity materials. They develop formulae for aquaria based on empirical data, using observation and measurement rather than theory

Magnesion-P
Brightwell Aquatics Magnesion-P
Concentrated Magnesium Supplement in Powder form for all Marine Fish & Reef Aquaria
- 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.
