I plan on drilling the tank and the overflow box and holding the inside overflow box on with bulkheads. I figure 4x 1" bulkheads with gaskets inside the overflow box and gaskets between the overflow box and tank so I can remove the overflow box to clean behind it. This tank is running as you can see so I'm doing it this way so there as little down time as possible
You aren't going to drill the tank while it's running are you?
That would be an epic YouTube video!
