Hey everyone! I have a 90-gallon planted tank with an FX6 filter setup. Recently I have noticed that filters flow has been extremely slow, in contrast to its usual high output. I have cleaned the filter pads (in tank water) rinsed out the intake and outtake tubes, but neither of these have seemed to fix the issue. I got the FX6 along with my 90 around a year ago from an individual who had the tank for an unknown period of time. Is this a simple issue that could be fixed? Or is my filter friend simply at the end of his life?
