230-gal custom Peninsula, seeking drilling advice

[DaddyFish]

Yes, I'm dropping serious coinage on a custom, because nobody sells a "standard" tank in the size I want, as a peninsula. And I'm omitting the brand for now because I'm seeking unbiased input.

Flow will be challenging in a 72x24x30 peninsula. Plus, I would like to have a Bean setup not just a Herbie. But that's a lot of holes across a 24" span.

Would you opt to stick with three drains across the bottom and drill for two returns up top on the end panel instead of passing the return through the overflow? That would make the return plumbing exposed off the end, but I could hide that with vertical blinding panels extended from the stand.

I am concerned about drilling four holes along the bottom end.

I would do the three along the bottom and two on the vertical panel. I think if you tried to do more than that on the bottom panel, it could potentially create too many weak points in the glass. Which would end up causing a catastrophic failure. I’m not too experienced in that stuff, but from what I understand, if there’s too many weak points in one small section like that, a simple over torch of a bulkhead would be enough to do you in.
