I'm working on setting up a 50g Rubbermaid stock tank as a frag tank. It's going to be plumbed to my main sump. I wantto set up a Herbie-style overflow so that it's basically silent, but I'm having a hard time making it work. I bought a Fiji Cube overflow, thinking the measurements would work out. Unfortunately because of how large and curved the lip of the stock tank is, I can't make it work without completely cutting the lip off and cutting down into the tank itself. I'm not opposed to cutting the tank a bit, but cutting down the inside of the tank risks leaking water because of how I'd have to cut to make it work.
If I used a HOB overflow box with two drains, I could still do a Herbie by making one the restricted drain and one the wide open drain. It would look ugly and I don't really want to put an external overflow on this system, but it would solve my problem.
Another option is just drilling two drain bulkheads into the back of the tank, but I think I'd have trouble getting a Herbie to work. I could put one drain about 0.5 - 1" higher than the other, but that's about all I can do since the tank is curved toward the top. The problem is most guides recommend 6" of difference between the restricted drain and main drain, so I don't think this would really work as Herbie drain.
Does anyone have any thoughts? I'm open to suggestions. I just basically want the tank to be completely silent and have an emergency drain.
