So I've been researching saltwater tanks for a bit now and after a couple weeks of planning, forum browsing, frequent trips to LFS, and online research I cleaned my dads old 30gal hex and got my equipment. however when I went to the LFS I was told that the way to go was CC and even when I threw out some arguments that I had seen in forums about it they still assured me it was the way to go. So being the newbie I am in the saltwater world I took their advice and set up my tank with CC the said 3in of it and my tank will run fine, but now im concerned. its only been 3 days since I set the tank up and I would like to know if I need to change it.
