Can anyone direct me where to get a warm pack for shipping corals? the ones I am finding heats up to over 100+ degrees (hand warmers). I might just buy one of them and keep them in the box, but outside the cooler.
Nino, there are many different ones out there. Can be purchased all over the place. They all have different activation times, life, and temps. They are taped to the lids to lessen the chance of moisture reaching them. Moisture will deactivate the pack.
They are touchy and it will probably take you a few tries to dial in exactly what you want.
