I've learned so much from this forum in just the past few days that I felt I should give something back. I started using a DIY C02 setup a few days ago and was trying to figure out a better (and cheep) way of diffusing the bubbles. I'm using a standard yeast in a bottle method pumping into an air stone. As I was attaching the air pipe to the side of my tank with a suction cup I thought to myself, "hey, this would work as a backwards umbrella pretty well." So I cut a hole through the middle of a cup, and ran the air line through the hole, giving the airstone a little umbrella for the C02 bubbles to get stuck under. Not a bad little method for only 10 cents.
