Building a sump/refugium

[cc_bruno]

The sump part will have quite a few sections and baffles in it, so, that part of it, I'm not too worried about, but, the refugium part, I am, as the goal is to have it as one large section, all in it's own. I'm thinking about using a full sheet over top of it, with two sections cut out of it, if that will support it enough to allow me to make it 18" tall.... but, if I can get away with not having to do that, then great, as the extra piece will come in handy for something else.

As for the 1/2" stock... that's an idea... will have to purchase that seperately, (I'm not getting the 1/4" from a manufacturer... it's a friend of a friend, so, what he has is what I have to choose from).
