I am still a little confused about the process of the sump and also, I wouldn't know how to set up the sump once i bought it anyways....the most i am confused about is the overflow tank on the outside and inside

.

If i can get some help trying to get the general information about hooking up the sump i would feel a lot better..
also, i read the article about sumps..but i still am missunderstanding a lot of the things.... I also read the kids
DIY article in the gitting started forum...again, that helped me to but i need a better understanding.... I think it would help If someone that bought and set up a sump could explain to me how they set theirs up(maybe with pics would help a little better too.)...but everyones help would be appreciated...so if you would try your best to help me
