If I was you I wouldn't waste much time with that if you want bigger allreay. Just learn as much as possible on water stabilty, and start preping for the next tank. Design and propose to fellow reefers, come close as possible to a perfect build. Then start preparing and the your year is up and you didn't waste time or money on stuff you might not be able to use.
Oh yea plumbing is easy I like to glue my negitive lap joints but it's not required.
