Hi all. I am considering the acquisition of some Spanish ribbed newts, and I'm planning an enclosure. I am considering using a large black plastic bin (like this https://www.homedepot.ca/product/hdx-102l-strong-box-tote-in-black-yellow/1000706729), with a number of aquatic plants and a spigot sealed into the bottom side edge to allow for easy water changes, as I don't plan on using a filter to avoid stress from water flow. I wanted to ask if anyone has used hydroton pellets as a substrate rather than just a drainage layer for this species? Of course I'd prepare the utilized beads before hand to make sure I removed dust and floating pellets. The ones I have seem to be around 0.5-0.75 inches in diameter. My concern mainly revolves around potential swallowing of the pellets. I know I could go "bare bottom", but I'd prefer it if the animals have some sort of ground to grip, and I've got a massive amount of the stuff, so I'm looking for a good use for it. I also like the idea of an adsorbent substrate, something that might sequester ammonia and other contaminants. I understand clays tend to do a pretty good job of this.
Any advice would be helpful. I've looked through several threads, but most seem pre-occupied with its use as a drainage layer, rather than as a substrate unto itself. If I'm mistaken in this, I apologize.
