Does exactly what it says on the packaging without harming fish or plants. No mess and easy to use. Have used this for many years and would definitely recommend as the best treatment to get rid of blanket weed and similar.

Didn't know if these would work. But as soon as they turned up,my mother in law said where did you get them from. She used them her self and wanted another for her filter, so before I had a chance to try them I had already given one away. Put into pond next day and weighted down with a stone,hope this help my pond now.

Seems to work quite well. Not as quick as the advertised claims but has made our pond much clearer over a two week period, is still improving slowly. The fish seem to appreciate it as well!
