I have a 120 gal
tank with about 150 lb. rock. I bought mostly base rock which was just Florida reef coral skeletons and two large (20 lb. total) live rocks from the LFS
. After chemistry started settling out and all of the rock was dusted with brown from what I assume was diatoms, I ordered a clean up crew from Reeftopia. They've been in the tank for almost one week and the rocks are just about the same pristine white that I started with.
Did I get the cleanup crew too early?
Will they starve? Or better yet, until I'm absolutely certain that the bad parts of the cycle are done and before I get any fish, is there something I should be giving the crabs and snails to tide them over?
Thanks in advance.
