Im going to try and get the rest of the tank done today..i have acrylic to make the overflow box, but im not sure i want to go with that or use 8" pvc cut in half for the box..square or half circle...hmmmmmmm..i hate decisions..lol..pics to come when i figure this out..
Just keep in mind with that big drain you need enough room to get in and clean it out. This is something that is easily over looked and can be a place for build up.
Still following along.
