I am new to the reef aquarium hobby and have building my system for quite some time now. Ive spent most of my time reading and planning on how I want to build my system. I have some questions for which I have not been able to find a whole lot of conversation on. Ive noticed a lot of successful aquariums with refugiums and a lot without. So here it goes, my first question...Oh I have so many questions... What are the benefits of having a refugium and those without? Also, what is the best way of setting it up? Im not necessarily talking about water flow or the location of the tank to the return pump but rather how should a successful refugium be setup? DSB, live rock, type of algae, small, large, etc.? I really appreciate any help or suggestions and I hope these questions dont sound too rookie like!--Thanks!
