    The link is to a video of a guy making a background. You don't need to watch it if you'd rather not. My question is that this guy is using cement and concrete on foam. This can't be safe for a reef tank can it? Thanks https://www.youtube.com/watch?v=cOb4uLQz-Dk

    My PVC plumbing for my sump was put together using purple primer and clear PVC cement. It's a week and a half later now and I can still smell the primer and cement smell in the pipes. Are they safe to use or do they need to cure longer?
