Bulk Premium Quality Activated Stone Carbon 27.5lb 20×50 mesh
Highly recommended Bulk Premium Quality Activated Stone Carbon! I’ve tried all the carbon made for this process and this is the BEST one yet. This one is even bigger than the last premium carbon we used to carry. It’s 20×50 instead of 20×40. Save over $40 by buying in bulk. This equals about 14 bags of 1.7 liter.
