Whare can i get some glass from?...if anyone has any thoughts on this please feel free to comment...thanks corey.

There are many ways to design a sump, and you will get various ways of doing so. I would suggest that you post a graphic of what you want to do, using correct deminsions and give as much detail to what you want to achieve. This way others can comment on it.

Filter socks - some use them, some don't... I personally do, as they do filter out particles too big for skimmers to break down.

Here is a thread that Grizz has on his build, I think you might find it useful:
