If the temp is already in the 60s I would take some action pretty soon.
It was for two days but we went back up to 70 and 80s

Hate to say it, but there's a reason you don't see people keeping tropical ponds outdoors here in the States.
Heating large amounts of water is prohibitively expensive.
Making lids for the pond AND building a little greenhouse around it would be your best bet.
Electric heaters would be the cheapest up front (you can buy a bunch of 300W Eheim Jagers for $25 each), but they will cost you a grip to run. A gas fired heat exchange system or a heat pump will cost a lot up front, but will be less expensive to operate over the long term.
If I were you, I would try keeping fish that can tolerate the natural temp swings in your area, unless you are comfortable spending thousands of dollars to maintain the tropical temps required for the species you are keeping.
you should look at getting a small tank less water heater. And some type of cover to keep the heat in. another thing you can do is insulate the out side wall of the pond.
Well up north dont keep tropicals. You could get an inline heater for a tractor. They will warm really quick so would put on a timer and see if it will work. $30 or so for the heater. 2" styrofoam walls and make a lid. I never read how hot they get but witha slow flow of water might keep it in upper 70s. Just a farm boys idea.
It can, two winters ago it was below freezing for over a week straightdoesn't stay that cold in texas for long does it? id just build a little greenhouse
