120 G reef tank setup....

For a 125 gallon reef you will need three 250 watt metal halides a nice protien skimmer sump system (euroreef). About 20 times turnover rate(circulation), lots of live rock at least 100lbs.Salt heater etc.
 
i wouldnt exactly say "all the way"... thats just what is recommended if this is gonna be a long term, healthy tank... which we all hope it will be.
