I am going to start a 55gal reef tank. I just poured my sand bed and wanted a second opinion on it. I used about 40 lbs of really fine dead sand on the bottom. 20 lbs of live sand on top of that. Then I put 20 lbs of live crushed coral on top of that. Will that work fine for aerobic and anaerobic levels? Or should I just mix it all up and let the two levels form on thier own.
