Hey y'all, This is my first thread on R2R but I've been a user since I officially got into the hobby. Growing up my parents turned a 55 gallon lobster tank into just a normal saltwater tank, but if you don't know lobster tanks tend to be closed systems so getting deeper into true filtration and health is not my stong suit. My current tank is a 5 gallon nano reef that is very healthy surprisingly, other than some scorching due to a bad light. Anyways, I'm currently building a 30 gallon reef tank as a show tank (I'm a broke kid fresh out of college) so I understand that a 30 isn't really a show tank but I'm working with what I got. The filter is a 10 gallon sump setup drawing water from overflow across a sock, biomedia, and a true filter. In between the filter and the outflow tank I'm going to install a refugium for copepods. I am wondering what copepods should I get to stock the refugium with. I can post pics of my tank if y'all want as well.
