in my opinion, ray(with no "S") with any tankmate is a bad choice for a 120.
Rays piss like crazy and they eat a lot (messy too)... thats what messes up your water. For filteration, Im not familiar with the ones u posted but I would set up filters for a 240gl on that 120... Its always best to over filtrate than what your Petco/NonPetSmart employees say.
Sounds like you are a new guy to MFK and rays bro... I highly recomm you do about a weeks worth of using the "Search Engine" and try to read everything you can about Rays, Rays with H2o changes and rays with filtering... this will save you tons of headaches and not knowing what to do except post a Thread with a Q waiting for someone to respond...
