Made some progress since the last update.
Bought a sump from a local reefer. But the darn thing won't fit under the stand

.
I think i'll just be using a 10 gallon tank into a sump/ refugium.
I was debating whether or not to just lie my lights across the tank, because I couldn't figure out how to hang it. There was no space to access the tank when it was over and it would just be too inconvenient for doing maintenance. So I built the light hanger from 2x4's and painted it black. The height of the light fixture can be adjusted via the hanging kit that came with it:
Here is the current set up:
The deltec skimmer will be moved under the cabinet and hanging off the sump once I get the sump all set up.
I have decided to go with a DIY pvc over flow and so far this is what i've got:
The check valve still has to be placed on the first "hump". I'll do that later today. It's waiting for me at the post office

. Nothing has been glued in place yet.
