Your post reminds me of the first time I realized that the small fortune I was spending on the "activator" and "stabilizer" for the Nature CO2 system was actually just baking soda and yeast. When I realized it actually worked, I just about jumped up and did a little dance.
Two 1 GA desktops, a 5 gallon, a 2.5 gallon, a 10 gallon, a 20 gallon, a 25 gallon, and two 75 gallon tanks, all planted.
I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.
