Great thread. Sorry about the losses and the move. Great new setup. I hope to enjoy a saltwater setup someday myself.
Yes, reef mud, from premium aquatics. I was looking at the ritteri specifically. Carpet nems, although beautiful aren't worth the loss of my fish.
Do some research on this. I have never used it but I have seen several threads about reef mud wiping out tanks. May just be improper application that caused the crashes but I have seen enough threads to make me think there are some issues to consider.
