re: #189 allegro

Ohhh wow, you guys rock. I can use my stove (propane - RV life has some advantages) to heat water to double bag in zip-locks to surround the aquarium and then wrap with a blankie. Thanks!

Even just foam layers will help - the water’s not going to lose heat fast with some insulation. But hot water can be stuck between it and the insulation and that will really slow the heat loss down.
