Good luck man. Sorry about that *******'s post(What are you gonna do right). Go for the FX5 if you can get it. Otherwise nothing wrong with an AC110 or a nice used 404 I can attest for both as great filters.
i found the filter but its a 304 only rated for around 50g so you will want something bigger i will keep an eye out i run into filters all the time.
you know if you have the room you could build one with walmart stuff and get a mag drive 9.5 to run it. or here is an option penn plax cascade idont have any experiance with rena but you could ask around. http://www.bigalsonline.com/BigAlsUS/ctl3684/cp17290/si1382699/cl0/pennplaxcascade1200canisterfilter
