Huntzman.....you are probably screwed on the FA for now because you have too much of it and the weather/water temp is hot....too much risk of a fish kill. If you do anything, try using 7 lbs. of copper sulfate crystals for each surface acre but you might want to cut that in half and see if you make progress.
Next spring, when the water temp hits 52 degrees or so, hit it with 15 lbs. of CS per surface acre.....that will get you started off on the right foot. Our place is in Macoupin county and i just finished the fourth dose of CS this year.....50 lbs. in our 6.5 acre lake. I do the 15 lbs./acre for the first dose and then follow up every 3 weeks or so with the 7 lbs./acre dose. We constantly battle FA during the late-June through mid-September time frame as we have plenty of ag runoff coming into the pond....our large fescue barrier just can't hold all of it back.
Our pond looks good now only because i have been really on it consistently this year. BM61.
