I swap out my foamies every other day!! I have three of them and I always have a clean/fresh one on hand. I turn off the pump, do a quick swap and turn the pump back on. Then I take the "spent" foamie to the sink and rinse it like crazy! Occasionally I will take the sponge and soak it in vinegar for an hour or so (gotta rinse like CRAZY again) but I feel it needs more than just a water batch. Those foamies can get REALLY rank really quickly. also before I yank out the dirty one I will usually try to do any stirring up before hand so that I physically remove as much YUCK from my tank all at once!!
Hope this helps MORE than it confuses!!
