Chlorine...makes sense, never thought of that, thanks.
Hmmm, now I am not sure which came first the chlorine vapor or the root rot because I for sure have some root rot along the tree line but since it's dead in places I guess that's normal. The round spots away from the pool may well be fungus. I have Heritage G for fungus so I may put some of that out. I've got Eagle and Honor Guard too if needed.
In places under the palms next to the pool the grass seems to be coming back SLOWLY after I trimmed the limbs back. Maybe as roots are established deeper it'll come back.
