Hello. I recently purchased and tore down 3 FX5s and a wet dry that came with a tank I bought. There are a ton of bioballs and they're pretty plugged up with detritus. I've tried spraying them with a hose and even shaking them in a next while running water on them without a ton of progress. Has anyone ever thrown them into a laundry bag, tied it and put them in the washer with no soap? Any other ideas?
