Bob,
Been there done that and still doing it.
Any possibility you treated before your water reached 60 degrees? Did you use the granular Cutrine Plus? Are you aware Chara can be resistent to treatment if you apply after it gets a good head start? Addtionally I seem to remember the directions say you may need to apply more, or more then once if it's resistent.
Personally if it was me I would consider adding grass carp as Chara is high on their favorite foods list. Don't expect them to clean it all at once and follow stocking guides regarding the size of the pond and % coverage of the pond. You may not see results for a year.
As far as treating algae that is no longer a problem, that sounds like a waste of money to me. But I could be wrong.
Never heard of the products you mentioned. Are they for aquatic use?
I fight Chara ever year in my 1/10 the acre trout pond. I can't use copper products and grass carp are not very effective in the cold water. The only way for me to control it is to rake it out twice a year and drain every two years after harvest. I don't know about your pond, but due to the amount of nutrients produced by the trout, my Chara grows three feet thick or possibly more if I don't keep ahead of it!
