return 1 1/2" bulkheads Can i add ABS?

[Hustler]

I was told from a few LFS the reason I pay double to tripple for those bulkheads is because they are made of "reef safe" abs...
but when you talk to say BRS they explain they all come from the same plant ect... I didnt even think this would be the same for piping.
