Tomorrow is my last final exam for this term (thank goodness), and I'll be moving all of my tanks back home. Since the exam doesn't start until noon, I was planning on breaking down all of the tanks in the morning and getting them loaded into the back of my car; the fish and filter media would stay in the room in their cups/bags inside a cooler so they stay warm. Then I'd be able to get off campus and be well on my way home before it gets too dark (highways and I don't get along at night).
However, I just considered the bacteria in the substrate - will it be able to handle the cooler temperature in my car for around two hours while I'm taking the exam? The forecast puts the temp in the mid- to low- 40's tomorrow, so it won't be freezing, but it's still not the toasty 80*F that the tanks are normally at. I know that the vast majority of the bacteria stays in the filter, but I'd rather keep as much of it as possible to reduce the chance of a mini-cycle when I get home.
Thanks for any help or advice!
