Copper gate valve OK?

[Rob]

I just installed a copper gate valve and remembered I'd read here that
copper is a no-no in ponds because it can kill the fish.

What's the opinion here: will one short length of copper (actually,
it's brass, that has copper in it) cause problems in my 400 gallon
pond? I wanted a PVC valve, but it wasn't available at the time of my
purchase...

Brass is better? Copper, zinc, tin, lead?
What concentration matters and what concentration will you get,
especially at a pH of 6-8? The Local Home Depot has a small pond with
so many pennies in it the water is blue. There's a half dozen fish
thriving in there. Hard to know when it becomes an issue.
Weird, huh?

if your pH is above 7.0 it is highly unlikely enough of anything will dissolve to
make a problem. Ingrid

Such a small amount, is IMHO, nothing to worry about.

I wouldn't worry about it. While copper is dangerous to fish, if you do
regular water changes I doubt the levels would be able to build up to
anywhere near a toxic level.

Copper is poisonous to fish, although it depends on how much gets into
the water. A 400 gallon pond is small, so it would be better to
replace the valve with a plastic valve.
