Copper is a heavy metal which, on the one hand, as a trace element is essential for plant and animal organisms, but on the other hand, in excessive concentrations has a destructive effect as a cellular poison.
Copper most often gets into aquarium water due to heavy metals in tap water or metal bodies, and from copper roof gutters into ponds.
Good water treatment preparations can bind copper.
Copper can be used to control fish diseases in certain situations.
