Odd WTB, but thought I'd try it out. I want to seed my tank with some live rock that has good biodiversity of life, minus all the baddies. Ultimately looking for some good microfauna like bacteria, coralline algae, pods, sponges, etc. Definitely want to avoid the bad algaes (hair is okay), asterina stars, aiptasia, and the usual culprits. Also, absolutely necessary to have ich / velvet free tank.
