Alright. I got a question. If i were to keep the calcium sand in the half of an inch layer in the tank, and just added the sand on top in a thick layer. Would that be okay so i dont waste the calcium sand or do i need to get the calcium sand out completely?
I use slate and fine sand to fill any gaps as a substrate for my leopard geckos, but for other reptiles ... you might want to play around with this idea ... or toss the idea around with other leopard gecko owners here.
Buy some of the lowest cost cat unsented crappy cat litter available, its clay.
Mix it with water to make a very thick soupy mixture.
Mix in your calcium sand, then form your substrate in any manner you like.
When it dries it will be as solid as can be, preventing any possibility of ingestion.
You'll likely want to play around with how much water, cat litter, calcium sand you use to get results that look natural.
I like to use more peat moss and only a little sand for reptiles that like it dry and enjoy digging, when done the way I like it holds a burrow perfectly and looks nice. This does not work real well for very humid enclosures though.
