It sounds like I'm between the proverbial rock and a hard place. I would much prefer to deal with short term pain to achieve long term gain. I don't really fish much in the pond, the trout are there to fill the role of the top predator. Also, I was under the impression that your low dose technique eventually kills ALL the CLPW, and it sounds like it will kill the Chara as well.
Rather than stop gap measures what would you recommend to fix the invasive weed issue? I assume I would use your low dose regime and then come in and plant beneficial pond plants? If you have specific recommendations on how to remediate this pond, or if you can point me to a "how to" on the forum I would greatly appreciate it. I've done a lot of searching but have had no luck finding advice for a trout pond in the Northern Rockies.
TIA
