I will be transporting my reef, for the most part its just rock with alot of
decent life on more than half of them. i will be using a 20ft livein trailer
type and make a one way travel-journey up north from southern california
with a 60 gal reef that needs to run off inverters. 300 watt heater will
kill the bateries in no time. how cold can i let these things get?


Heat Packs may help a little, but that is a long and potentially cold
trip.

If it were me, I would hook up the inverter to your tow vehicle while
traveling... This will keep things charged up. If you use decent
wire (12 guage or so for a long run), you should be able to keep
enough juice pumping into your batteries to keep things going.

Wrap some good insulation around everything to minimize heat loss...
