rusting check valve?

I bought a check valve or one way valve from home depot

this model Flotec Brass Check Valve 1 In. - TC2502 at The Home Depot

I was told it was not going to rust .. it is brass but i looked at it today and it has a green rusty build up on it..

It is directly in my sump tank connected to my return pump.. is this going to be an issue? will copper metals mess up my tank?

 

copper in a tank=death

 

how much copper would have started to come out from the brass valve.. it was setup for probably a month.

 

btw my snails and shrimps are still fine and i have not seen any difference in them or numbers dying

 

Theres probably not enough for worry, honestly if it was in the tank you would have NO inverst left

 

well i ripped out the valve and am headed back to home depot tomorrow to return this thing.. hopefully i can find a plastic one.. im gonna see if my lfs can test my water for copper.. what level is off the scale for total failure in your tank?

Any sort of carbon or filter media i can put in my sump to help ?

 

Any really, you are fine, if you were not fine all your inverts would be dead already!

 

thanks.. i sure hope its not as bad as i am making it out to be, starting to hate this hobby..if there is a scale amount of copper in the tank.. what can i do to reduce it.. if anything?

 

Nothing really once its in a tank you really cant use that tank anymore as it gets into the silicone and leaches back out....BUT like i said if everything is ok now then your fine

 

brass is a zinc and copper mix (alloy)so not a good idea on a reef tank,but like oceanparadise1 said you would already know if any leached as all your inverts would be dead.use plastic!
