heat pack question??

[Emoney]

how many hour heat packs do you guys use???

Ive used 2 20hour heat packs in shipping boxes during this cold weather and had great success .

I need to order more, just wondering if i should stay with the 20's or go with 30 or 40 hour packs.

I've used 2 of the 20 hour ones in the past as well, and had no problems. I used to ship mostly zoas, and never lost any.

Here is a pretty awesome "Heat pack study" write up by Beakerbob. Might shed some light on the use of 2 heat packs....some actually raised the water temp to 89 degrees :squigglemouth:

I usually buy the 40 hour heat packs.
