ewest There was a distinguished gentleman at last years conference (Dr. Anderson?) who was kind enough to spend some time with me and suggested Rice bran or Cottonseed meal for a natural fertilizer. Could not located rice bran and Todd Overton, on one of his trips down, suggested cottonseed meal also. That was our final step to clearing our larger pond. Used 2 applications, 600# and 400#, from shore by hand and achieved a bloom. When the bloom subsided the water cleared even more! I also want to note the FHs and BGs ate the meal as it drifted.
Also note our water was very soft prior to 2.5 tons of gypsum.
I too will be awaiting a report from cwooten and more info on the boulders.
Dr. Anderson (sp?) also suggested to those who "hand feed daily" to keep a bag and spread a little daily when feeding during warm weather.
