What heat packs do you use?

[Michael43]

does everyone use uniheat? I sent a frag out recently in a very small well insulated box with a 20 hr heat pack and the coral got there at 60 degrees. Maybe this one pack just didn't work well?

I use uni heat, but I feel like the 20hr heat packs are super weak in terms On heat and lasting

I always go with the green 72hr that way if there's a issue the coral had a better chance of surviving also.
