My Solenopsis have completely outgrown their mini-hearth and need to be moved in the next week or two. I have a ten gallon tank that I made a lid for with acrylic. I'm would like to spend around $50 for the whole thing, but I can go a little higher if needed. I've done some research, and from my understanding, I need a drainage layer, a layer of charcoal, a seperator, and finally, the soil. I have some questions:
1. I know ants need a sand/clay mix, but how would I make this? Can I gather some dirt from a place where colonies normally nest?
2. The lid I have right now is pretty well-fitting and has only a few gaps caused by the plastic bending a little. How can I give it a tighter seal? Weight? Silicone?
3. How can I create sufficient ventilation with the lid on, so that the oil barrier isn't rendered ineffective?
As, I get closer to actually building it, I'll probably have more questions, but this is it for now.
Thanks in advance!
