Plumbing, A few new Questions

[GreenSpottedPuffer]

Ok that helps, thanks. Is your overflow acrylic with black egg crate? That looks like how I might be doing mine.

Another thing Im wondering about, is my skimmer. Its a PM Bullet 2. I would prefer to have it in-line and not in the sump. Is this possible? I feel like an idiot asking but I have no idea??? If I did put it in-line, where "in-line" would you recommend and how is it done?

I know a lot of my questions are pretty basic but you guys are helping so much! I really want to get as much done this weekend as possible but have been really stuck
