Fail! I can't seem to edit my post.
I was saying that there is an extremely limited selection of PVC at my local big box stores, so almost everything I bought was brass. Aside from the weight, are there any issues with this? I have brass fittings feeding water to my refrigerator for drinking, so I'm assuming it is safe for my aquarium inhabitants too. Do I need to clean / treat the brass in any way before sending water through it to my aquarium?
