Well, we have been treating the algae with Crystal Plex and it has gone pretty good so far. We started with a bay that had a huge amount of growth and monitored the oxygen levels. They really didn't dip that much. Then we looked at the rest of the lake and realized that there was just a thin layer of algae on top of emergent coontail making it appear thicker. We treated the rest of the lake with great results. At day 2, oxygen levels are close to normal and 80% of the algae has been zapped.
One unintended, but beneficial, effect is that we have applied this stuff in just high enough concentrations to zap some of the coontail as well. While we want to leave some of this growth for the fish, we did simply have too much and needed to thin it out. Much of it is slowly dieing and we encouraged the neighborhood to pull out this stuff to help with oxygen depletion. Should be relatively easy since the roots have release and it is just floating on top.
Thank you for all of your help.
