Can anyone tell me of any web site that states that copper is not
safe to use all the time in a "all fish aquarium".
Did you know that most saltwater aquarium stores are useing copper in their retail aquarium systems?
I found a s/w aquarium store in Carlisle, Pa. that does not use copper
in his fish tanks.
I take my hat off to him.
Check out his web site.

Would you by a fish from a store that does or does not use copper?
