brass needle valve

want to use a brass needle valve for the air intake for my protein skimmer. Since it wont be in the water will it be ok to use it? I am worried about killing my corals. I know brass has copper in it and copper is horrible for corals. what do yall think?

I would avoid putting any metalic objects in the tank other then high grade stainless or titanium.

Stainless is safe and gives you a no-worry install. Anything with brass is a gamble.

If it isn't going to touch seawater and used to regulate air, there should be no problem. But advice already given to stay away from metal is good.

Id use a plastic valve just to be safe but i dont think it would affect water without water running thru it

Stay away from brass....period. A good quality stainless steel is your best bet.

In my sump there's always a lot of splashing and stuff. Even my skimmer gets salt creep to te bottom of the collection cup. So I personally would stay away from brass cuz it could splash and rust it up quick, and could be a chance rust will fall into the water or other problems like that. I personally wouldn't take the chance, but it's not my tank! Lol
