Toxic to birds - listing description is inaccurate!
The Amazon listing says this product is safe for birds, fish and pets, but the label clearly says "this product is toxic to birds." I would absolutely not have purchased this if I had thought it was toxic to the wid birds who drink out of my pond. Also toxic to bees. Very, very disappointed. Returning.

It's a magical algae remover
I'm not saying it's magic but it is absolutely something! I've used it two times within this week both times after just a few minutes algae starts coming to the top for you to scoop it out. I've kept my pumps running and after I scooped out what I can scoop out it usually settles on top of the lid and I'm able to clean it all out. Water looks disgusting while it's going on but once the pumps run for a while it goes back to Crystal Clear and none of my fish or frogs have died. Definitely recommend if you have algae growth it's obviously doing something to it.

Messy container
The container "safety instructions." says do not get on skin. The lid was lose and chemicals were all over the container. It was impossible to "not" get chemicals on everything because of the lose lid. Just opening the box, you could see the dust flying out of the box.The chemical seems to work, but the vendor should do something about the container

Removal of bucket lid
I'm sure it was a glitch in production, on the lid there is a red button to push in order to unscrew the lid. There should have been a hole on the out side of the lid. That was missing from mine.i cut the lid off and transfered the bag to my old bucket. As far as the Alge off gos, it's great stuff.

Doesn’t work
This item did not work as advertised. It did not alleviate the green string residue in my pond, even though I use twice as much as they recommended.
