I have been hit with quite a few PMs asking to re-start this thread with less #######ishness from me.
So--with adin's approval---let's try this again.
Before we begin--please--this will be based on personal experiences. I don't do this for a living. But I do love the hell out of this hobby and I want to inspire more hobbyists to grow and share their coral. The most important thing we will get from this thread and discussion is understanding---and hopefully a historical reference for future shippers.
I myself, don't typically use ice for shipping. Why, you ask? Well, it's my personal opinion that ice is cold.
I don't know if a small amount of ice will kill coral or not. I usually ship small pieces in small boxes.
I've used an ice pack once upon the request of an ebayer--and it worked fine. I look at it as another hassle--another "supply" and expense--and in my experience of shipping frags for years and years---unnecessary.
Grow and share your coral---don't be afraid to ship. Log in your experiences---and maybe change my mind about cold packs.
In the meantime---I will be running my non-chilled shipping experiences all summer long. Post here and join me.
