Hi EB, welcome to reefs.org. I would suggest looking at the CPR BakPak series, or AquaC's Remora models. I'm sure Brandon and Matt may have good (probably better) ideas as well, just give 'em time to catch up here.
Also, please, don't take this the wrong way, but posting in all capital letters is considered somewhat rude, as though you're yelling, on the net.
