If you use Curtine Plus for treating Chara the granules are the type to use not the liquid. Read instructions on the bag for appliation rates. Maybe use granules to get Chara under control and knocked back then add a few grass carp for long term control. For southern waters start with grass carp at about 5-6 per acre. Then after 2 yrs add an extra one or two per acre ONLY IF the Chara is still abundant. After the g.carp have been in the pond for 5-6 yrs you may need to stock a booster (second) stocking of g.carp of about 3-4/acre. Old g.carp often slow down in their eating habits.
