Yes, typically Chara and Filamentous Algae are easy to control, but not in trout ponds where copper products are a no no. As you may know trout are very sensitive to copper products. Since my filamentous algae is temporary and it does uptake nutrients and ammonia I can live with the problem. Additionally I treated the trout pond with Hydrothol 191 last fall after removing the fish, and hopefully that eliminated the small pond weed which is the real nusiance. I also drained the pond and removed 90 % of the dead plant material.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
