The other predominant plan is Chara, which covers most of the pond bottom. Prior to the Chara and CPW I fought a constant battle with FA. Since the Chara and CPW gave me clear water and no FA I've just been living with it. The CPW is suddenly spreading very aggressively so I'd like to try this low dose Fluridone, but what will be the effect on the Chara? Is there something I can plant to replace both of these weeds?

The pond is well fed with no outlet. Stocked with Rainbow trout. Aerated at the 8' depth.


Unfortunately if you wipe out both the Chara and the CLPW you will be fighting the FA most of the year. I'd try just wiping out the CLPW and the Chara in the areas that you want to fish.

Treat the CLPW in late September or early October with the Fluridone.
