If you don't mind me asking, how deep is your pond? I wonder if either good circulation (daily turns) or shallow depths help keep the water temps up on our few cold days because of solar tranfer.
It's encouraging to hear you have had this unexpected success. I'm west of Conroe, so close enough to perhaps get similar results.

I have a small pond just north of Houston that has some TP that have managed to over-winter for at least 4 years. I wasn't surprised that they survived a mild winter or two, but this long is a shock. I switched over to Optimal BG Jr feed this year and these TP love it!!
