Scarf,
By Aaron's PM, I'm guessing you guys were trying to reach me today but I left my phone at work after I turned it off during a meeting. Sorry about that but I also had told Aaron that I might be tied up after work today.
Having said that, it might be a good thing that you didn't make the trip all the way out here cause I just remembered that the guy who originally ordered the sump through Reef Exotics from MRC might have had more than just the 2" off the width & height to fit his 75g stand.
I came home pretty late tonight and went to measure the sump and it's actually 30" in length, not 36" like the standard model.
So the sump measures like this:
30"L x 16"W x 16"H - these are outside dimensions.
Inside dimensions are:
Refugium area - 17"L x 7"W
Incoming drain area - 17"L x 8"W (this is where the 3 baffles are and there is a 1" drilled bulkhead in this section for an external skimmer pump)
Return flow area - 12"L x 15"W (this is where you can sit an insump skimmer if preferred and there are 2 bulkheads drilled in this section for external return pump or pumps. 1.5" & .75"
Sorry for the miscommunication, if you still want it LMK. If not, definitely not a problem. As mentioned before, I would just keep this for future use.
