Hard water, is it safe for tarantulas?

[galvantulatrainer26]

Hi all, just wondering if hard water is safe for Ts, as my taps produce hard water. I’m currently giving my tarantula filtered water from a water bottle at the moment as I’m a little nervous about hard water and if the minerals could be potentially dangerous for a spider

Hi
I give mine boiled and cooled tap water without issues. Its not very hard where I currently live but in past I have lived in places with liquid rock coming out of the tap.
When you boil it some of the minerals will go out of solution and will settle on the bottom of the kettle, pan or whatever tou using. Tip it slow without much disturbance and discard the last bit.

I just use bottled water, but i came from a heavily urbanized area so I treated our tap water like it was a montezuma's revenge dispenser, lol
