Zinc is a necessary element for marine organisms. Zinc concentrations of .1ppm to
1 ppm cause lowered growth rates in zooxanthellae. A concentration of 0.1 ppm reduces
fertilization in the Faviidae family of corals. Natural levels should be maintained,
as it is essential for photosynthesis and for the formation of calcium carbonate
by corals.
Some crustaceans can regulate the amount of Zinc intake but at high levels this
ability is lost, thereby allowing toxic accumulation. As with many heavy metals,
the toxicity of Zinc on invertebrates is increased with decreased salinity.
Maintaining natural levels of Zinc is recommended in your system, which can be achieved
through regular water changes using a good quality salt mix.
Lab Aquatics recommends a pH of 8.4, an Alkalinity of 9 dKH, a Calcium level of
400 ppm and a constant temperature of 78ºF for most reef systems. Maintained using
either a Calcium reactor or Kalkwasser dosing and carbonate buffer. This note is
added here as studies show a direct correlation between excessive Zinc uptake and
reduced salinity.
