Sorry to hear man. I lost two tanks to a forest fire here in Colorado. I learned the first thing that kills the tank is a lack of flow. So even if you can have one pump on a battery back up or something that might work. The next would be a heater, but in Florida I don't think it's gets cold enough yet to effect the corals. They can survive many days without light, but without flow they basically can't breathe.
dang, I am sorry. If you are ever put in this position again, just put your rock/fish in buckets with a bait bubbler and take the powerhead/heater and light with you.
You don’t need a glass tank. Just put everything in a tote when you arrive wherever. If you had to fly out, You can bring live fish and inverts on the plane as well.
You can just buy distilled water wherever you go and mix it with some salt form petco or what not.
