Thanks for the answers. I was out of town for a week and this fungus problem got out of hand when i got back. It was disheartening to have to pinch off all the affected new leaves when there are only so few of them newly growing. I am also battling string algae in the larger kiddie pool which I am wondering if was the cause of killing two of my lilies....ie strangling them to death. I have noticed that my dwarf parrots feather cuttings that I transfered to this pool are also struggling due to the string algae, they don't do as well here as they do in another tub free of string algae.
