Power outage or lost of power. What do you guys recommend to heat up an aquarium system for an emergency example I live in a condominium complex that down the street a a car accident. happened someone crashed into a electrical pole. and I lost power for two hours I wanna be prepared for next time. Don’t wanna lose my life stock. I know I cannot connect a power generator gas powered because I live in a condominium complex. If anybody can give me some ideas. that would be great I would appreciate it
