hi there, i am new to this site and also new to the marine hobby, i have had fish tanks through most of my life but never attempted a marine setup, i litterally am starting from scratch, i am looking around at the moment for 2 steel girders to place in my walls which will then hold a 5ft x 2ft x 3ft (hopefully) as i hoping to get the setup correct first time round any help from you all will be very much apreciated, thanks in advance
