Sorry I'm multitasking and should have elaborated. I have done a bunch of research for both but it seems as though everyone tweeks these things there own way and I would like to try and gather as much information from you guys (the experts) from personal experience. I appreciate your help thanks for the links

We use stand pipe Durso's in our fish room by the way, but you are on the right track with herbie and bean drains. We have much lower flow rates than you'll need/have.
