yup I haven't had any health issues with the algae I was just wondering. Just wondering if it worked to prevent having to scrub out 100 water cups all the time. It's just me like u said "unsightly" it drives me nuts.I use copper sulfate as an algacide. Exposure duration or concentration needs to be increased. Algae in water bowls unsightly but does not appear associated with health issues for me.
