I don't think I got the right stuff
Hi,
I've got the beginning of an algae problem. I'm working pretty constantly to keep it at bay, but the surface of the pool is generally going a bit green-ish at least once a week. So what I could find was HTH super algae guard. I'm going to use it as recommended on the container, but when I look at the ingredient list, it's got 2 of them at 30% each making up the 60%. I guess I'm posting this because the formulation may have changed - it's a slightly different name than your picture.
