Livestock arrives in and out of stock very regularly, depending upon availability of the item from the source. The more rare and expensive items are often difficult to hold in stock, and can take time to source, so we generally require a deposit to locate and purchase the extremely rare items
Fluorine is one of the main micronutrients contained in seawater. In a closed aquarium system, skimmer and filtration media remove fluorine deposits from the water, therefore its supplementation is necessary. Fluorine participates in the calcification process and supports skeletal tissue. Sodium fluoride and calcium fluoride are the building material of coral skeletons, therefore fluoride supplementation is necessary in a reef aquarium. Balanced fluoride supplementation, effectively strengthens the blue and white colouration of SPS corals, as well as highlighting the fluorescence of most corals. Contains traces of potassium and iodine.
Recommended Fluorine level in marine aquariums is 1.0-1.5 ppm
