a penny to stop algae growt?

[ryknier]

I read someplace that to stop algae growth,or to not have as much, throw a few pennys in the tank, the presence of copper, or a metal, algae can't grow. Is this true? I really have to write these sites down when I read an interesting article!!

Copper will impact more than just algae--I certainly wouldn't use it in any of my tanks. Crustaceans in particular are sensitive to copper.

Controlling algae is a matter of controlling the nutrients available to it.

Agreed, Copper is a big no no. Never intentionally add it to your tank. It will kill algae, snail, plants and it won't do your fish any favours either.

You shouldn't put anything metal in your tanks for a long period of time.
