My tadpoles do a great job of eating FA and I have lots of them. I added GSH last year because I remember someone saying their pond was full of them and they didn't have FA. I also have lots of plants and so far I haven't had even a trace of FA on the surface of the pond while most of the ponds near me have or have had FA. I walked the pond yesterday in chest waders and my spatterdock lilies were algae free on the stems down to the pond bottom, and when I would stop wading minnows would surround me. So with this total war against FA I've won so far, but the big test will be when we have the 100 degree index heat.
