Brightwell Aquatics Alkalin 8.3 comes in 250 mL, 500 mL and 2 L.
Brightwell Aquatics Alkalin 8.3 PowderåÊOverview:
Alkalinity, also referred to as carbonate hardness or buffering capacity, is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. In an aquarium, weak acids formed by oxygen respiration and the decomposition of organic material gradually deplete alkalinity. If left unchecked, the alkalinity drops below a critical level and pH begins to fluctuate more wildly than is normally suggested (a daily pH shift of +/-0.2 is normal in marine aquaria), causing stress to livestock. Alkalinity is also depleted by reef-building organisms during the production of aragonite (~60% carbonates by weight), and is therefore very important for their rapid growth. Maintaining the alkalinity in marine aquaria between 7 - 12 dKH (2.5 - 4.3 meq/L) will generally maintain pH within the desired range.
Brightwell Aquatics Alkalin 8.3 Powder comes in 250 g, 500 g, 1 kg and 4 kg.

Brightwell Aquatics Ferrion Overview:
Photosynthesis is carried out within cell bodies known as Chloroplasts. Iron is utilized in the electron transport chain within the chloroplasts, and is therefore required by photosynthetic organisms for continued functioning and health. In marine aquaria, these organisms include macroalgae (such as Caulerpa, Halimeda, and Penicillus spp.), marsh grasses and mangroves, encrusting calcareous algae, and the symbiotic zooxanthellae and zoochlorellae that reside within the tissues of hermatypic corals, clams, and their allies, as well as in some sponges. In effect, the availability of iron becomes a limiting factor in the rate of photosynthesis, and hence the rate of nutrient uptake and growth, for these organisms.
While each aquarium will require different concentrations of iron, a good place to begin is within a range of 0.05 - 0.10 ppm; this will generally provide sufficient iron for the photosynthetic organisms present in the system. Some aquaria may require, or benefit from, iron concentrations greater than 0.10 ppm, however greatly exceeding this level is not recommended. The best method of determining the optimal iron concentration for an aquarium is to begin at 0.05 ppm and then gradually (i.e. over a period of weeks) increase the concentration as warranted by the appearance of the aquarium. Phosphate is a substance that encourages growth of algae under the environmental conditions commonly found in marine aquaria, and overdosing iron in the presence of excessive phosphate may result in algal proliferation; for this reason, the concentration of phosphate in a marine aquarium should be maintained as close to immeasurable as possible.
The rate at which iron is extracted from the water is determined by the stocking density of photosynthetic organisms, type of lighting, and other conditions. Once the rate of iron uptake in the aquarium has been determined, the proper dosing rate of this product can be easily calculated.
Brightwell Aquatics IodionåÊOverview:
Brightwell Aquatics Iodion sizes: 250 mL, 500 mL and 2L
Brightwell Aquatics Kalk +2 Product Overview:
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.

Brightwell Aquatics Magnesion Product Overview:
Brightwell Aquatics Magnesion sizes: 250mL, 500mL, 2L
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).
