I used bottle water for spraying all my reptiles. Even for my water dragon to swim in. I was told by the vet and by other experienced members that 80 to 82 was fine for my veils so that is what I had it at. But if they had pre existing parasites that should have shown up in the fecal... However we now know that the fecal that was done on them when they arrived my not have been done by someone that knew what to look for (or so that is what they say now they they were questioned about it).
