You want a non-toxic anti-freeze. RV antifreeze is made for the plumbing systems of campers. You can buy that or similar stuff labelled swimming pool antifreeze from pool stores. The RV antifreeze is sometimes a little cheaper.

I'd like to hear from Chemgeek on this. Proplyene glycol is the major ingredient in RV antifreeze. Significantly different from Ethylene glycol which is the green stuff used in older vehicle cooling systems. EG is sweet and animals tend to to go to it, nasty poison.
