So i have an extra tank and some other things laying around and thought that I could build a frag/grow out tank. I was going to use a HOB filter with my choice of media, and then i was going to build an over flow type area. In that area, im curious as to how much of pressure a 1 inch drain would create. Was interested in using it for a form of extra flow for my lower tray. Any POSITIVE input is appreciated, just be nice as it is a limited budget/space/parts build.
