So last year I used Aquathol with the lowest side of the recommendations on a single side of my lake - with the expectations that weeds would grow on the other side and leave the beach side clean. However, that killed all the weeds in the lake. So maybe this year I should leave the Aquathol go and just allow the GC to do their job? Or should I try to net some of the GC out of the lake? I would say right now I have an easy 6+ feet of clarity, but I'm getting ready to add some aquashade to darken the water and help prevent the FA. I use the Cutrine Plus for the FA as well.
