Water

Keep a reef tank,and with two filter systems(one 4 element,one 5 element),and have all the purest water needed.;)

Ive been using regular tap water out of the faucet and never had any problems. I really don't see the necessity of providing drinking water.

I've been using reptisafe, but once its out, im just going to tape water. I mean watching 100's of youtube vids all the big breeders aswell have them connected to a hose! For the most part they wont be there slurping it up right away anyways, so itll get its time to distill.
