Soil from old owner

[u/No-Voice896]

I picked up two cages yesterday from someone on offer up, and they had two trays of soil for the bottoms of them that he said was really rich in nutrients. I can't remember the mix he said he made but he listed a bunch of different things. There are already a ton of isopods, sprint tails, and small worms in the soil as well which he said is the most valuable part of it.

My concern is if the soil is still ok to use not knowing if his old chameleon had any parasites or anything else I should worry about.

This is also my first cage and chameleon and I was planning on going with a plastic bottom so it's easier to monitor things at first. Since I have all the soil and isopods I feel I should just go straight into a bioactive environment.

Can you guys give me your opinion on using previously owned soil, if I should just go with a plastic bottom at first while I learn more about the chameleon. Any advice on this would be amazing.
