Thank you for the replies, it seems the more i read the more i am scared of this project I am tryin to keep the cost perdy much as low as possible with diy stuff. The biggest expences besides the livestock of course would be the rock, glass, skimmer, calcium reactor, and pumps. A few of these i am not real sure i need like the calcium reactor and the skimmer but i guess i just have not convinced my self that i don't need these items. But again i really am diving in to the unknown with this whole thing I probally will start with getting the tank built and going from there trying to leave as much room for expansion in the sump as possible.
