I wasn't aware of the GreenClean product, but after researching it a little, I think I may order a bucket to do shoreline maintenance of my FA. I tried a copper sulfate last year on some BGA (bluegreen alg) and it worked, but I didn't care for the toxicity. This stuff can be diluted and sprayed for that.

Worth a try, I think. Especially since it wont hurt the other plants. I've got some widgeon grass trying to take hold that I'd like to keep as well.
