Hi Everyone! My name is Rosemary aka Ms Slick, I'm in Arkansas and have a 75g, 35g freshwater, and 10g saltwater. I have had my 75 for the past 32 years. This past week I broke down and said what the heck I'm goin for SALT on the little one just to see if it was as horrible as everyone told me it would be... well so far, it has been such a pleasure to me I wished I had started salt a long time ago! So now I am addicted!! I would love to take the 75 and start a reef tank... but not sure if I am ready for that. Any suggestions to help me out here?? Like how much weight in rocks and such will that 75g take? Suggestions on filters and etc..?? Thanks for helping out!
