I'd prefer the idea of vacuuming it off somehow. Ideally, it should go to a
canister filter with pads to catch all the loose junk, and it should have an LED
near the nozzle end so you can see what you are doing.

Of course, I've never seen one, but I've always felt that would be the best
option.

I don't do the toothbrush or scrubbing method. If you'll endure the
backbreaking manual system each day for about 2 weeks (14 rough days), you'll
end up with some really good results, ime.

Hi Marc-
Yes, I read the article a while back and have employed the "manual
harvesting" method you described. It works well, but my back can only take
so much of that. My tank is an "in-wall" type of setup. I have to lean in
from the back of the tank. I was thinking of scrubbing the rock with a
toothbrush. What do you think of that idea?
