I've been using the same filters for a couple of months now in some of my tanks.

These are the common carbon-sponge type that come with Regent HOBs.

About twice a month I swish them around in a bucket of water and try to rub any clingy stuff off of them.

Is this ok, or do I need to plan on changing them soon?
 
They can be cleaned until there's not enough of the floss-lke stuff to filter out crud. When you do change them, you might want to swap them out a couple of weeks apart so you don't pitch all your beneficial bacteria.

HTH,

dont change the sponges just clean them. if you shove a bunch of bioballs or biobales into the filter it would work even better, thats what i did for the 30-60 filter into my 40 gallon.
 
Once the padding does where down you can just use some filterfloss, from my experiance it filters better then the original pads
 
I chucked the carbon and just use sponges and filter floss. And I just rinse then every week. Be doin it for a year with no problems.
