Has anyone mixed sand coco and Tightbond III to make a background for there viv. I did a project volcano with my son using gs then covered it with tb3 sand mix it dried rock hard in 2 hours. So I got a idea let's mix sand coco (50/50) and tb3 see what happens it dried in 3 hours rock hard. So I tried again sand (25%) coco (75%) and tb3 that was last night and today its dry so less then 24 hours. Anyone see the harm in using this for there background for dart frogs. The sand I used for the volcano was red and brown repti sand because I wanted a darker color.
