I have a Whisper 60 filter and it appears as if the bio sponges are preventing proper water flow. With new filters in place water is still coming out of the "your filters are dirty" middle portion of the filter. When I remove the sponges the water flows properly. I am wondering since I've rinsed them out with water and squeezed prety much everything outta them I can and it all has no effect. What is the best way to clean these sponges? Does anyoen else have this problem?
Thankyou for your time.
