#ed_op#DIV#ed_cl#OK, Sump is up and running.... I like it alot, a little noisy on the return pump but its tolerable. I want to start setting up the refugium now, and want to know what you guys think about setting it up. Main tank has 3" bed of live sand 150# of LR, should I go with mud, or sand ? or combo of mud bottom under sand ? What do you guys (the experts) suggest !! ?? #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#Algae choices ? Livestock ? #ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#J#ed_op#/DIV#ed_cl#
