Has anyone ever used ABG soil mix from Joshs Frogs?

It's mixture is as follows
  • leaf litter
  • sphagnum peat
  • fine long fiber sphagnum
  • fir bark
  • Charcoal

I used this in my terrarium because it was fantastic for plants and looks great, but in hindsight i'm wondering if I'll run into problems in the future.

Should I switch my pacman to a different enclosure with coco fiber?

If I'm worried about impaction how should I prepare it's soak? I hear honey is good do I just mix it into the water?
