Well as acquiring donations is a bit more difficult than I anticipated, I am donating my 46g bowfront that I installed the Caflo overflow on. This overflow will ensure that the classroom doesn't flood in the even of a pump failure or return blockage. As Cody pointed out, the overflow box can be used to house the heater an possibly other equipment so the sump/fuge has more room.
Here are some pics. I finished the plumbing last night. All I need now is some of the clear tubing to go from the PVC to the fuge. The plumbing is at an angle as the overflow is on the same level as the tank. It will need some tweaking at setup.
Again, if anyone has a sump/fuge or tank that is max 17wide x 24 long to donate, please let me know ASAP. I will come get it today as I need to get the tank set as soon as possible. Most likely I am going to at least drop off the tank on Monday and try to get sand/live rock/water in it on Tuesday or Weds, so if anyone has some circulation pumps and a decent heater let me know. I can come get them today.
If things don't accelerate, I'll just drain and take over my 37g tall....
Here are some pics of the tank.
