Cecil:
The pond in front is the one that has the Sago problem, right? The Chara is limited to the back one?
Correct. I used to have some Small pondweed ( Potomogeton pussilis) in the trout pond but don't see it anymore.
I may also get some grass carp and put them in the front pond. I can always shoot at them if they come at feeding time. Or catch and release them like George says.
