J.W.,
Thanks for passing on that interesting information concerning the use of cornmeal to promote a "bloom". I assume you use this method as an alternative to fertilizing the water with a commercial liquid or granular fertilizer. I intend to do that in the spring, but I was told that the water was too cold to use any kind of natural means to get rid of the fil. algae this time of year. The Univ. of Georgia extension agent suggested the cutrine plus or comparable product. He also cautioned that the cutrine itself would not cause a fish kill, but the oxygen depletion resulting from the decomposition is what did it. I followed the dosage recs to the letter and ended up using a third of the chemical to do the job.
Take care
