I'm getting my first T soon. A GBB, and I was wondering if you need to treat their water? I have used Reptisafe for my Hermit Crabs for over a decade. It says on the bottle it can be used for Tarantulas but I don't think I've seen anyone talk about this online. Not that I have come across yet anyway. Do you use a product like that or do you give them water straight from tap? Or bottled water? Thanks.
