What do you mean by "floating debris"? If you mean the film on the top of your water than you need some surface agitation. A powerhead near the top portion of your tank will help with that and also good to help get gases out of your water.

Possible solutions:
Increase Flow
Get a filter sock
Get open water swimming fish (To eat the detritus)
Get hermits/ detrivours (To eat the detritus)

A sump is going to be your best bet but if that won't work for you then the above should help.
