[Riverside Reptiles]

Interesting. Thanks for the information. In 20 years, I've not had an issue with a perlite impacted animal. But I suppose with darts being so small it could happen. But for most geckos anyways, it works quite well for aeration. I guess that another big difference is that my purpose is for mostly arboreal animals where as darts spend a lot more time on the floor of the enclosure. Anyway, some interesting info. I'll probably try adding some charcoal next time I make up a batch. Thanks again. Learn something new every day.
