The chara is back. After paying $1600.00 to get rid of it last summer, it's growing again. I'm just at a loss as to what to do. Any grass carp that I now add will be expensive, but that probably is my only choice. I guess any solution will be expensive. I really had no intentions to keep a lake of this size fertilized, even though I know that would help in the problem.
Not necessarily. Once the excessive Chara is established you will only enhance the Chara by fertilizing unless you kill it off. It's actually a form of algae btw, but you probably already know that. ( But didn't you say it's fanwort in an earlier post?)
Perhaps you need to give the grass carp more time. It typically takes a year or two to see results with grass carp.
As a long time sufferer of Chara I have a lot of experience with it.
On the plus side it holds a lot of invertebrates.
