Okay so there has been some progress on the tank!
I wasn't expecting to have a tank until august at the earliest, but it looks like I have one now!
I came across a shallow 40 gallon tank that was the exact same width as my current sump. My sump is a shallow seastar tank (26" by 19" by 12" high). It is only a year old and is pretty much the dimensions that I was looking for! SO I popped the baffles out and put them into my new sump.

I siliconed the baffles in with aquarium sealant and am currently waiting for it to dry. I plan on leaving it until Wednesday and then using it. I figure that will be enough time for it to cure, since it says only 24 hours.
