Dilema what to do

[Skimmin]

So im getting ready to set up my 6ft 300gal. I have approx 220lbs of pukani rock from Eli at fijireefrock. Sure is nice looking stuff. Im having trouble trying to figure out what i can fit it all into to get it circulating before my tank gets here. Its a lot of friggin rock! Im not sure how critical it is to cirulate/cure it or if I should bleach it before i put it in my tank... Should I clean it more? There seem to be so many opinions of what to do I'm just not sure... Theres visible decay in some of the rock and some smell but nothing horrendous. Can anyone let me know what I should do. I've never used dead rock to start a system before.
