Well I went with a Sandless bottom Its been running for about 5 months and I just added fish after the first of the year, I have 50 lbs of Life rock, that's been in the tank for about 2 months. The lights I currently use now are 2 24" marine lights. The Fish I have now are a Dottyback. Gold Clown Goby, Coral Banded Shrimp, and Cleaner snails and A Peppermint Shrimp. The Coraline is starting to take off, But I know the lighting is not enough.
