Ok, Quick Subtrate question. Looking for input out there. Seen a mix of information. Clam species, Gigas, maixima, Squamosa, and Crocea are the goal. Currently have Crocea and Maxima's. I am running a small crushed coral (not quite sand) now. Going to a bigger tank. I can run small rubble/sand mix or sand/Aregomax mix. Any suggestions out there?
