Chaeto Without Sand??
I have changed my mind about adding a sand bottom to my refugium after what you told me. But I am adding Carib sea mineral mud, a one gallon container, not sand. My refugium is 12″x14″ in my sump. I made my sump using the pressure locking sump baffles article. But anyways, will this be enough mud to cover what I need in this relatively small space and will a refugium this size have a positive effect on a 120 gallon system.
