Hi all. I'm looking for opinions from the experts out there on how to properly start my new 180g set up. I'm going all dry base rocks and sand to prevent pests and hitch hikers. So for my 180g, I added 4" of dry sand and about 100lbs of base rocks from Marcorocks.com. Is it necesssary for me to add some live rocks to seed my rocks? Some live sand to seed my DSB? Or these aren't necessary at all since they'll become life after cycle? From what I understand, with DSB, I don't want to get criters that like to shift sands such as nasarius snails, gobies, sand shifting starfish, is this true? TIA
