Well I thought I would wait a couple of weeks before I pulled out the rock and put the starboard down. Got home from work, took one look at the board and started pulling out the rock. There is still a bit of dusty fine sand floating around on the bottom but it will be out in due time. Well, added a sump, upgraded the skimmer and now bare bottom. Next will be a better circulation system. All this after I thought I knew what I was doing. Wouldn't have gotten as far as I am (long way to go yet) without everybody here asking questions in all the forums and giving good answers. I enjoy reading all the threads. Thanks for the informative reading.
