Something is growing like crazy and taking over the sides and bottom of my pond. It covers the bottom in large mats and grows up to the surface.
It has long evergreen like needles that are very fine, I thought it might be milfoid but doesn't have groups of four as discribed in my handbook, it also looks simialr to a najas or chara.
I have put cooper sulfate an also tried cutrine on it but it doesn't seem to make much difference.
Anybody have any suggestions or ideas?
