Yeah, with the second I can see having to be very careful to match the flow rates between the two tanks. As far as I'm aware, it's not as easy to just drill a hole in the side of the tank. If that was an option, I could just put tube at the waterline, and have gravity do all the work returning water to the bigger tank.
Either way, these are just at the vague-plotting points. lol

I went in and measured the tank. Diameter from flat edge to flat edge is 11.5", and from point to point it's 12.5". And the height is 10.5" at the sides (the center does have a part that comes up so it can be lit from below, and not have to filter through the substrate). Ran through a calculator, and it looks like it holds just over 2 gallons. Definitely need a sump or the like.
I've also been doing a bit of googling here and there for inspiration for the sump. This diy will likely be my main inspiration, though this one looks simpler to make. I just don't like the look of having the sump visible. (Unless there's a beautiful refugium involved. I have a dream tank that would involve such a thing.)
