Hi Meredith, Hope you are feeling better! I have one filter with a sponge over the intake but I haven't figured out how to clean it without putting all the crud back in the tank any suggestions? Here is the trick I use. I take an open baggie, slide it over the sponge, and remove the sponge with the baggie over it.
