That is great news !!
I was concerned that you would have YP popsicles.
You might get by with out a heater but I am not sure about that if you get a long real cold spell. What is the temp. of the well water? Seems like I saw an aquarium heater that floats so that it won't touch the sides and does not get to hot. I will see if I can find the link. ewest
