In recap; I'm putting together a 120 gallon reef with a sump. I currently have about 80 to 100lbs of Crushed Coral/Argonite from when this tank was a Cichlid/African Lake tank. My LFS owner suggested I go with maybe a 1/2 inch of the Argonite/crushed coral and then add 80 to 120 lbs of Live sand on top of the substrate. Is that necessary? Can the reef survive without Live sand??? whats everyones thoughts??? can I just re-use the CC/Argonite??? I've boiled all the Crushed Coral to clean it. ...
