Do you have any suggestion, please, for the removal of blanket weed in a pond? There are fish in it. I have been doing it manually but with very limited success. Many thanks
If you want have fish and clear water, you probably need to install a UV-filter to kill the algae and a biological filter to use up the nutrients. You can also plant lots of water plants, any kind, because they compete for the nutrients, and they also shade the water, reducing algal growth.
Jabbing the trails of blanket weed with a long cane, split at the end and twirling it can get rid of large amounts quite quickly, but will have to be repeated until the problem with excessive nutrients is solved.
