Anyone have experience moving a dsb, or at least know the proper way to transfer the sand to it's new home? I'm assuming I should just fill the new fuge w/dead sand and add the top inch or so from my existing system. I'm worried that if I add the whole established bed I will wreak havoc on the tank(by mixing all the layers), but to be honest, I've never done this before, and I'm unsure. Any suggestions would be appreciated
