Ok just getting started and I'm in no hurry to populate my tank. I have a 90g with 20g sump/refugium, 600gph overflow, 2 1300gph overheads and 300w heaters for tank and sump. I have 40lbs of Key Largo rock and another 100 on its way plus my ro/di system. What process is needed to start my system if I use dry rock only? Does this Dr. Tims start the process? Can i add live rock to this if I decide to add 10-15lbs of live? Looking for pointers or pitfalls with this plan. I'm also looking to build a 30-35g sump/refugium once I find a cheap tank. Thanks for any help.
