Looking to add a sump

[EvilTwin]

I have not ultimately decided about the sump. I played around with the overflow assembly and it took me a while to figure out how the thing was going to get primed. I think this will be a nice overflow. I'm thinking about building my oven sump from acrylic using one of Melev's designs. I'm adding my new 40lbs of LR to the tank today now that it is done curing. Sump is next.
