Want to know about Fauna Marin’s Elementals Series?

The Elementals series is designed for use with regular ICP analysis. The Fauna Marin ICP analysis helps you to keep your aquarium perfectly supplied.

In addition to the measured values, Fauna Marin ICP analysis provides you with all necessary dosage recommendations including the salts of the macro elements calcium, magnesium and carbonate hardness, we also offer a number of  elements whose function is essential in saltwater aquaria.

In contrast to trace elements such as iron, zinc or vanadium, macroelements are present in seawater in concentrations of more than 1 mg/l. These include, for example bromine, boron, potassium or strontium. The function of these elements can be very different. In the knowledge database on the Fauna Marin website you will find an overview of the respective function of the individual elements.

Macroelements can be contained in many different substances and can therefore also enter the aquarium water. However, despite their necessary concentration in the water, their deficiency can cause considerable problems. An adequate supply of all important elements is therefore indispensable for a healthy reef aquarium.

Our single element solutions consist of purest raw materials, which are produced with the appropriate organic or inorganic compounds depending on the function of the elements. For production and quality control we use our coral farm and of course our own ICP laboratory.
