Thanks everyone who has helped with my 3 55 barrels set up, my last issue on my 320 is where the holes are drilled, in the center of the sides. I was going to run both these as drains but not sure about making a wall to protect the stand pipe. Also if I do it's going to take a lot more space then if it was in the corner. I'll post a couple pics. I have a couple ideas, I would just run a strainer at the bottom of I can figure out how to stop the drain if the power goes out. Also thought of running an elbow on the bulk head and reroute the pipe to the corner. Would cover with sand and small rocks. I also have no problem blocking the holes and running a DIY overflow like Joey did on you tube with the black paint. Let me know your ideas.
