In the past month, the clear intake tube of my Whisper 3i filter has started growing some sort of brown algae/diatom inside of it.
I've had issues with algae before (hair algae and pinkish slime), but I've been able to scrub them off and have them go away.
However, because this algae is inside
the intake tube, I can't reach it to scrub it off. The best I can do for now is blast it with scaldingly hot water. That gotten a lot of slime and goobers out with this, but the brown spots remain.
What are my options? I've heard soaking it in bleach will help, but I'm kind of scared to try that.
