That picture isnt in my tank but I do have two drains. I have 2" drains. Not sure if Im going to cut them down to 1.5 with limiting plumbing but that is the size of my bulkheads, so if I do ever want 30x turnover I can do it.
Does anyone have an article describing the build of each? Im only partially educated on the two designs but it sounds like a Herbie is better and I'd like to just do it right the first time if I can. Is a Herbie simple to install?
