Box fillers
Cellulose Wadding = (absorbs wetness). Most shippers in my experience do not use this, but from what I’ve read on FedEx is it’s a requirement. They want to know if a bag leaks, there is something inside to absorb the water without it leaking all over the place. It is a cost, so must weigh the benefit and vs what the shipping companies really require.

Peanuts – Most shipments I receive have this, and neither cellulose nor absorbent. They are great fillers and keep the contents in the box in place. Nothing against this, and not sure if I would reuse when I get them.

News Paper – Cheap, can absorb, and readily available. Looks cheap too and can compact when weight shifts. Mainly use to wrap ice or heat packs
Most shipment I’ve received has a large plastic bag to prevent any leakage that may get the box soggy. So all the fillers, and bags are inside the big bag. This is an added layer of complexity if dealing with the heat pack, since not sure how well heat will get inside the bag if the packs are outside. Food for thought.

Heat and Cold Pack
“If the temp is moderate 50-70 I don't use a heat or cold pack.”

“If temperatures are predicted to be dropping below 40 or rising above 80, it is usually best to delay shipping until conditions are more conducive to the survivability of the animals.”

I’ve read about 24hr or 48hr packs. (( Where to get them? )) Make sure the heat pack is warm before you close the box. Packs need air to stay warm ((so is a hole or gap left?)) Preheat pack for 30 minutes before you seal it in the box also ensures it works and is not a dud. Wrap it in newspaper or Uline sells neat envelops.. but that adds a cost. It was stated that if you wrap pack in a lot of paper if you only need a little bit of heat, wrap it less if you need a lot. Not sure what the determining factor is between knowing when a little or a lot is needed… Also, remember these heat packs need oxygen to stay warm. if you completely seal the styrofoam box with tape, and the outer carton, then the heat pack will be limited to the O2 that is trapped in the styro only. I’ve read to always try to leave one side untapped, or poke a small hole in the styro lid, to allow some air to enter, but heat packs are always cold when I get them, then they heat back up a few minutes after getting air outside the box. Lastly, remember to use a heat pack rated for a little longer than the expected time in the box. If you pack the corals at noon, and they won’t be delivered until 10:30 the next day, a 12 hour heat pack will not be enough. One of the references stated to always try to shoot for about an 8 hour cushion, so if you expect 12 hours in transit, look for a 20 or 24 hour heat pack. Also, try to use enough heat packs for the size box you are shipping. Again one of the references recommended use 1 - 24 or 48 hour pack for each cubic foot of space in the box you are am using.

For cool packs: spend $1 at local store and get a gel pack and freeze it. Wrap it in newspaper and to not allow it to contact the bags. Also for a "cool pack" I have just used a bag of ice wrapped in newspaper. Be careful with it though and don't use it unless you expect the temps to be above 90. If its going to be that hot have the package held for pickup at the local FedEx facility.

At what point do you consider heat packs? Any temp below 40F? I’m not sure how to determine the route the package will take to check this, Cross that bridge when I get there
