This morning I noticed the un-sprayed algae didn't look as bright green as it did before spraying.
I'll rake it out.
A combination of rain & busyness prevented me from raking out the dead algae but not to worry - the algae is gone! It sank to the bottom! Three days is all it took & I only spray about 20% of the algae to do it. Nice to know there are products that are environmentally safe!
Thanks to all for the great advice you shared.
