Hey, Blaine, yeah, I've seen a substantial reduction - a real one this time around - after that Whitecap treatment (did I mention that Greg Grimes gave me a sweatheart of a deal on it just for being a PB member?

).
There is still enough there that on a totally calm day, it will spread a very, very thin layer over perhaps a quarter of the pond, but it's thin enough that it's not too visually troubling. With just a little breeze, it tends to all stack up on a shoreline into a nice, tight little area where I'm sometimes able to scoop a little bit out just to take a small manual removal stab at it.
We're getting into some pretty chilly nights coming up here and I am hoping that this will be enough to finish it off earlier than it was last year.
An interesting observation has also been that the Whitecap (did I mention the great deal from Greg Grimes?

), of course, knocked out pretty much everything else in the pond, but the chara has just started coming back in the past few weeks, to the point now that in many areas it's a few inches tall/deep. I've noticed a lot of small fish hanging around in it where it's close to shore, so it may be a great addition for the winter by providing a place for the YOY fish to hide out, at least for awhile.
Thanks for asking, Blaine.
