Anyone know why Flourish Excel kills algae?
Once I got my CO2 in balance with my light and fert levels, I found that excel was very effective at killing off the stubborn BBA and a little hair algae that had stopped growing, but wouldn't go away. That is great, but it bothers my that I don't know why.
I hesitated to use excel at all since I am also not really clear why adding another source of carbon (which is what it is described as) would be helpful in a tank with injected CO2.
Any thoughts?
