I have the Animal Plastics T8, but have not set up a bioactive enclosure within. I've been interested in the idea as well, though have opted not to go that route... for now. So, I have no experience in bioactive setups to answer your question, but I will say that the T8 has a low lip before stuff starts spilling out. I think for a bioactive setup you're going to need deeper substrate, making the T8 challenging, if not outright impossible, to achieve.
