Green Clean does exactly what it says it does! Anyone who gave Green Clean a bad review did not take the time to do their research. This procuct is a GRANULAR algaecide and NOT a liquid like AlgaeFix. The manufacturer clearly states that it has to make CONTACT with the algae to work. It is completely SAFE for all pets and wildlife if used properly. Once this granular algaecide makes contact with water and disolves...........it can't hurt a flea. It would most likely hurt a bird if the bird tried to eat it in its white powder state, but that would have to happen within a minute or two of adding it to your stream and waterfall (which is VERY unlikely since you would still be standing right next to the pond after adding the product, and most birds are not that brave). Litterally within seconds, the white powder disolves and in this state, the product is harmless to wildlife and your pets. Do your research, use the product properly and as stated in the directions and you will LOVE this product!!! Say goodbye to string algae!!! Green Clean works great and does as advertised!!!

What an easy product to use with the benefit of great results in killing the string algae that had accumulated on my waterfall and rocks. My string algae was dying immediately. The added benefit is that it is safe for my dog once it is dissolved in the water. Great find!
