Watch for it to appear in your other filters.
I would clean that FX5 Until it would pass a surgical inspection and run it on another tank in the house for 3 weeks to cycle it.
Then it goes back on the combo tank and their regular filters get bleached.
You are probably going to fight this stuff for a while. I got the pink stuff in a research lab with 20 Emperor 400's running when I was a grad student. I could do nothing to treat the infection beyond clean the tanks as it would have really messed with the protocol of the experiment I was running. I had to break down, hose out and and re-establish flow in every filter every 48 hours. I did 10 filters a day, every day for about 3 months. I couldn't go anywhere for even an overnight... I HAD to clear the filters daily. It would take me about 4 hours to do the 10 filters. The day the experiment had run its course..... the fish went into a holding bin and I used a full gallon of bleach on those filters! Bleach never smelled so good!
