Find Stockist Calcium


Calcium is a crucial element in seawater, vital in various biological and chemical processes. It is essential for the formation of skeletal structures in marine organisms, especially corals, molluscs and certain types of plankton. Calcium also interacts with the carbonate to regulate the chemistry of seawater.

Stable Calcium levels are critical for the health and growth of hard corals where it is used in calcification to build their calcium carbonate skeletons, variations in calcium can affect both coral growth and skeletal density.

10 ml of Calcium Zlement increases the Calcium concentration of 100 litres by 20 mg/l.

Magnesium


Magnesium in seawater plays several important roles in both biological and chemical processes. It is the third most abundant ion in seawater with a concentration of around 1,350 mg/L.

It is a vital ion in seawater, with multifaceted roles in biological, chemical, geochemical, and ecological processes. It supports the health and functioning of marine ecosystems, influences the carbonate chemistry and mineralization processes, and plays a crucial role in maintaining the stability and productivity of the reef environment.

10 ml of Magnesium Zlement increases the Magnesium concentration of 100 litres by 10 mg/l.

Boron


Boron in seawater contributes to alkalinity and plays a significant role in the regulation of pH through its ability to be present as Boric acid or Borate ions. Maintaining levels around 6mg/L in a reef aquarium will support coral health by aiding pH regulation in their tissues, stabilising molecules and cell membrane function which will affect nutrient uptake and overall coral health.

Observations have shown that with adequate levels of Boron in a reef aquarium SPS can display bright and almost metallic colours.

20 ml of Boron Zlement increases the Boron concentration of 100 litres by 1 mg/l.

Strontium


Strontium is a macro element which is present in all reefs around the world.  
Although its physiological effects are still being studied, there is evidence that impacts on health of animals. Strontium is associate to calcification of coral skeleton and general coral health and therefore important for maintaining good growth and coral health.
Strontium is a macro element that gets depleted from the water in our tanks fairly quickly.

It is important to check Strontium levels through an ICP analysis and ensure its stability by dosing a Strontium supplement as needed.

Naturally, Strontium concentration ranges around 8-10 mg/l.

Strontium Zlement used in conjunction with a regular testing procedure, allows any reefer to make corrections to Strontium levels ensuring the levels in their tank water stay within the best range for their friends.

10 ml of Strontium Zlement increases the Strontium concentration of 100 litres by 1 mg/l.

Potassium

Potassium concentration in natural seawater is relatively stable and consistent across the worlds oceans. The typical concentration of potassium in seawater is approximately 390 to 400 mg/L.
Adequate levels of this element are needed for optimal coral growth, nitrogen metabolism, and physiological function. Potassium also plays an important role in the colour and health of corals.

10 ml of Potassium Zlement increases the Potassium concentration of 100 litres by 10 mg/l.

Bromine


Bromine is essential for the formation of certain biochemical compounds in corals and other marine organisms. 

It is also believed that good LPS/SPS colouration, health, and florescence is linked to Bromine as it can influence the symbiotic relationship between corals and their zooxanthellae, it is significantly important to blue colouration.
Low Bromine concentrations can lead to loss of colour and growth, especially in sponges, soft corals and gorgonians. It also aids in neutralising harmful substances that could otherwise build up in coral tissues and cause damage. 

10 ml of Bromine Zlement increases the Bromine concentration of 100 litres by 5 mg/l.

1 Litre Bottle

IMPORTANT NOTE: The use of Ozone and the dosing of Bromine should be handled with care, as both substances together may lead to the formation of Bromate a toxic compound. Therefore the ozonised water should be passed through an activated carbon filter.  

Sulphur/Sulphate

Sulphur is a significant element in ocean chemistry, affecting both biological and chemical processes. The concentration and different forms of Sulphur in the ocean play crucial roles in the marine ecosystem.
Involved in the photosynthesis process which is essential for phytoplankton and corals its availability can influence the metabolic and catalytic activities of these organisms affecting the overall health of the ecosystem. In addition to this, adequate levels of Sulphur are crucial to microbial organisms that facilitate nutrient cycling.

10 ml of Sulphur Zlement increases the Sulphur concentration of 100 litres by ~3.5 mg/l.
