Thanks. Good idea on the water bottle. Will keep an eye on the temp. My tank is 65g, 4ft long. I think 2000gph at the surface should be ok but not suredunno how big your aquarium is. If you can. Wrap your aquarium in a blanket. Heat water in water bottles to float for heat. Repeat if necessary. Pour water in and out of your aquarium every 15-30 minutes to circulate water. You can check pge website for power time updates. I have some portable equipment if you need.
