I live in michigan and most around us dont have power due to an ice storm. We have been lucky so far. It made me realize tho how unprepared I am in case I had to go without power for a number of days. Ive got to much invested in my fish tank to just let them die. My tank is a 125g african tank. What to I do if the power goes out for days? I dont want my temperature to drop too much. What can I do to keep it up? How do I keep the water moving and oxygenated? Is there anything else im not thinking of?
