So I have decided that I am going to build a sump tank for my 55 gallon display out of a 10 gallon tank I picked up at a yard sale. I was wondering if there were any post on here where someone had already built one that I could look over? I'm just curious for dementions an whatnot. I know that my Reef Octo skimmer requires 6-8" of water but I still need to think of a way to put in a filter from the return out of the overflow box. (Yes, I didn't drill my tank) also wondering how much space is really needed for the refugium compartment before I get into the return pump section. I know this is kind of a jumble of crap in here but I got a lot of questions and didn't know exactly where to start. Thank for any and all help you guys give.
