I use it in my pond every summer. I add a tablet every week and it always works well. I usually buy from Menards but ordered these instead for convenience. Something is wrong with this party. It doesn't clear it up and on top of that it created a weird movie that won't go away. I'm not sure if I got a bad batch or if the product has changed, but I'm not happy with it.
