Nowadays in all new buildings it is common practice to use water pipes made of copper. These copper pipes can present a serious danger to all aquarium inhabitants.
Newly installed copper pipes do not yet have an insulating layer of Carbonate deposits coating their insides. If particular pipes are not being used and water is being held in them, substantial amounts of copper can be leaked out into the water. Since dissolved copper is highly toxic, it can lead to the poisoning of fish.
A similar danger exists in newly installed hot water boilers or in those where the carbonate coating has recently been removed. For, those who live in apartments or renting, this is especially important when you notice renovations occuring.
If water is allowed to run off for a few minutes before it is used in the aquarium it may be sufficient to flush out the dissolved copper.
Usually within a year a layer of carbonate deposit will form, which prevents any further dissolution of copper in the network.
