Cecil, you said you water without heat was 62°F. What was ambient temp in the room?
About 64 F. in the dead of winter. I was told by a very knowledgeable person that it's typical to have unheated water about 2 degrees below ambient temp. Don't ask me why but I have some guesses.
Right not it's sitting at 67 without a heater. I have a 1000 watt heater on order.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
