I also believe it was the plants. While the cold temperatures certainly
help I have seen Water Hyacinths clean up a pond in one day in the middle of
summer. The first time I saw a truly crystal clear pond it was in the front
of a store and when I asked what they did for filtering and such they said
"nothing". The upper part of their pond garden (2 layers) was filled with
water hyacinths. I could not figure out why mine were not flourishing as
these were and after trying various things found it was the fish eating the
roots (filter mechanism) away. That is when I started an upper pond with
only plants and a few rosie reds for mosquito control. It works better than
anything I have ever seen.

I really believe it was the plants, the roots are loaded with gunk. Joann

It is now almost winter and my pond finally decides to clear. You all
remember me complaining all season about my pond looking like the
Potomac
River, well it is now clear.What created this awesome change in the
water
clarity, chemicals no, UV no, was it weather, no! I added more Water
Hycianth to the pond last week ( I got a great deal local for end of
season)
and it cleared in one day. I am now sold on Veggie filters. I am so
happy.
I even see some babies I didn't know I had. Joann
