Does anyone use the black tubing? I have a problem with that real thin, snotty build up in the air tube from my overflow. Its almost transparent, so its hard to see it building up in there. I'm amazed at how much of that stuff I clean out of a 4ft length of tubing. I use a blue tubing now, and keep it out of the light as much as possible. Just wondering if the black stuff helps at all?
