i want to get a hang on the back refugium for my 60 gallon hex reef tank. right now i have caulerpa in my display tank and i want to take it out because i am going to get a fish that eats micro algae. i also want to get a green madarin fish and i want to have a place to thrive the copepods in. my question is what do you think about this hang on the back refugium i found at drsfosterandsmith.com http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3727+3618&pcatid=3618? also what do you guys think about miracle mud in a refugium?
