I wasn't exactly sure if it was working for me since I have the hair algae problem and i can't figure out what is feeding it. (My nitrates are finally down to 5ppm) I have about an inch of crud under the chaeto. I'm wondering if I should siphon it out. It looks like muddy fish poop. I also have a million long / soft tubed feather dusters in there.

Should I clean it all out?

Thanks,
Angie
