Got my HOB fuge going, just need a softball sized hunk of cheato, possibly one full of pods so I can get them colonized quick for my mandarin. I'll be around Watson Rd. in St. Louis this coming sat. and can probably meet someone at Tropical World Pets. I'll let whoever can be there know a time later in the week. Also, is having sand/refugium mud necessary? I just put some live rock rubble in mine and was wondering if I need to order some or not. If so, what is the best? Thanks a ton everyone!!!
