ya i'll try to get more pics, it's too hot to even go outside at the moment.
it has what looks like 2" bulkheads 1 in each corner, sorry tried to do an ASCII drawing but it came out skewed
it's got an interesting overflow 4-5" wide across the entire left side of the tank and stops about 1/2" short of the water surface looks like it can easily be removed if you take off the silicone, the black piece is just a piece of ABS plastic siliconed on the outside so it can be just pulled off, i was going to do it myself but don't want to have to scrape the silicone off the glass to make it pretty.
bulkhead on the left goes straight down to the sump, there was a holder for commercial media pads but i removed it because it was broken.
right bulkhead is the return, it's plumbed with flexible pvc, skimmer is T'd off the return line also, i think the skimmer is kinda neat, it's a cupless type designed to be plumbed directly to a drain or bucket so it's pretty low profile and very effiecient,
the sump is some sort of plastic. probably holds atleast 20-30 gallons but i'm not positive on that, it's quite large 24"24" x 10 or 12" tall
