I am using 100% dry rock...well, I cycled about 90lbs for a year and added 2 chromis about 4 months before my big tank got started. I also put 100lbs of Marco rock into tubs of RODI water for 4 months prior to putting them into my tank...with 50%monthly water changes. I used Prodi-bio from the start and have no Phos or Nitrate problems...SPS seems to be doing fine.
