seriously, not more than 400 is abit hard to get the stuff u wan.......live sand cost abt $50 per pax, n i believe u need abt 4pax. rocks will be ard $5/kg - $16/kg depending on grade......if u gt low budget, try to get those normal sand instead of live sand. rocks can try buying from reefer who decom. salt also depends on ur budget. but if u wan to speed up ur cycling, use nsw....after that use salt mix for water change. never use tap water to mix ur salt, else u going to face alot of algea prob later.
