Internal Sump...with Plywood?
Hi, first post here, though I've been reading for months.
I just bought a 20L to upgrade from my current planted 10g, and I was inspired by a member here to try an internal sump.
Since I may someday attempt a plywood tank for my turtles, I figured this could be the first baby step in learning the process. I have enough plywood laying around that this won't require me to purchase any, so it seemed worth asking about. A black rubber coating would also serve as a nice background, to boot.
So first, what are people's thoughts on this? I realize I'll likely end up spending more money to do this than buying a used canister, but I like the idea and it sounds fun to try.
