I have a 125gallon I am setting up and I was wondering what everyones preference is as far as cost, cleanablity and efficiency?? I found a External stage 5 canister on amazon I was thinking about it is rated at 520 gph. I also found a Toms Aquarium RP3 Plus Wet/Dry filter, it is a 700gph. I am thinking about a couple Oscars or other cichlids for my tank. I have never had either type of filter so any input would be great. I have read and read and read all the posts I can and still can't find a definitive decision deciding factor. PLEASE HELP!! Thanks
