Hey guys, need some advice. I currently have a JBJ 65g rimless with the stock setup with the filter socks and media. I want to add an external sump. I know I need an overflow box and obviously a sump. I have a fluval flex 37 that I can use as the sump. What are some recommendations people have for a hood overflow box and which company makes good insert to create the sump or would I just be better off buying a premade sump? Also, what other items are needed to get this set up? Any help is greatly appreciated
