Use a skimmer too, if you have an extra one. Run the skimmer as a
wet skimmate and keep an eye on both SW levels and salinity. Water changes, carbon, temp and circulation, water changes, lighting, water changes, heavy skimming, water changes... Oh yeah, dont forget to buy some extra ASW mix and a big barrel to make some extra ASW, you'll need it to make the WATER CHANGES... (so you may need an extra heater and a powerhead or other submersible for mixing the ASW)
I personally always buy rock uncured and do it myself, as there is a ton of stuff that will not make it through the curing process that MOST folks do when
curing rock that add much diversity to the tank (and add some pretty kewl critters to your system). Treating the rock as if it were some live photoautotroph will give you many surprises that normally wouldnt show up in your system.
It IS worth the trouble, as many of the creatures that will survive are not ones that you could purchase in a LFS.
