Subject: query re tannic acid and algae

Hello,
	I am a high school student who hypothesized that the tannic acid in 
the Burning Bush tree (Euonymus atropurpureus) can kill the algae that 
grows in pools. I noticed that a B.B. stick had fallen into my pool 
and the algae around it had been killed off. Knowing that there is 
tannic acid in many types of trees I guessed this might be it. My 
experiment proving this theory worked, but I cannot find any 
information to back my theory up. If you could add any input at all it 
would be much appreciated.

																								
																																Sincerely,
