agree with Epleeds. you need some time to get the tank gets mature. if you add fish and the coral at the same time , there will be cycle hike which will stress the fish and coral.
If you get the water and the live rock from previous owner, that's different story. (bit safer than starting from the scratch.)
PM me. I am not an expert but I have been kept the tank for 17 years.
I pass by Springfield time to time.(lived there for 15 years near Huntsman blvd).
