Brass fittings ok for a freshwater tank with shrimp?
I am currently in the process of setting up my 75 gallon tank. I have an fx5 for filtration and am plumbing it with a rex griggs style reactor for the co2. I got a 2" piece of pvc, I purchase a t-fitting that was 2x2x3/4". So then I needed to get from threaded 3/4" down to the barb fitting for the co2 line. The only thing that home depot had for this were brass fittings.
My only concern is that the brass may leak into the water and affect my shrimp or fish. Is there any concern with this?
