Well, I haven't done any treatment since I have recently added my YP, WE, and BC to the pond and want to have more than 0 minnows left in the spring.
I wanted to update everyone how CLPW grows in our cool northern waters with hard, alkaline PH 8.5 or so... the stuff just doesn't quit! Water temps at 41 near the surface, sun out full bore, and oxygen bubbles streaming up from the plants still! That is amazing photosynthesis in my book. There is a patch of CLPW that is already about 30x30 that must of spread from a turon earlier this summer. The plants grow FAST even in November, and never quit in the summer.
I do see gobs of minnows swimming in the plants, and they seem to have done an amazing job of clarifying the water. I can now see down a deceptive 8-9 feet now fairly well, making the pond look oddly shallow. Cool to see schools of FHM swimming in different size classes at different depths.
It does appear to be a great plant for cover, but lousy for fishing and swimming. I will be getting some grass carp this spring to keep it somewhat tame, so I am guessing 2 of them for now just to keep the stuff from taking over the whole pond. I want some plants for a healthy pond, just don't want a green blob.
Now if we can only get some precip. 0.75" of rain for the entire month of November is unheard of in these parts.
