Aquarium Gravel Into Tank

[azzmilan]

Hey everyone any help would be appreciated.

I am planning to keep a little pool area with my Southern Angled Headed Dragon (Hypsilurus spinipes). In the pool area I am going to keep it reasonable shallow but I was wishing to inquire if I were to use gravel from my aquarium, (water has been tested, perfect) , would there be anything zoonotic that could transfer from my aquarium to my lizard.

I most likely will just wait a few days and get some new gravel and plants to put in there but just as a general interest .

Thank you!
