I have a 42 Gal. w/25 lbs of LR, I heard about Nature's Ocean Live Sand and started up my tank with it. Going on 4 weeks, I have 2 Chromis, 18 assorted Hermits, 2 Sally Lightfoots, 2 Emerald Crabs, 5 Peppermint Shrimp, 10 Turbo Snails, and 5 Cerith Snails. My Ammonia, Nitrites & Nitrates are all at 0 (Zero). You may want to look into the different Live Sands at your LFS. Do some research and find you will work for your set up.
