hey, try a search, it might be asking alot for someone to type out just for one post all the info you need to read to learn about and build a sump/refug.
search for diy plumbing 101
that should give you enough info for you to decide where to go from there. i am in the same boat and bought an acryllic setup from ---- and put it together and it leaks. so i bought a 30L glass tank from the local fish store today and am gonna get a glass company to cut me some baffles and silicone them in.
there isn't one post or one way that has been proven to be better than the others. i would just read, read, read and study about the process and exactly what is trying to be accomplished and you can come up with your own decisions on how to do it.
i am actually taking a little bit from three different setups to make mine just like i want it.
hope this helps
