you cant buy ph 7 water at least ive never seen it besides calibration liquid not sure if thats even water though you have to buy a ph meter and ph up and down in order to make perfect ph. if that was the case some companies would be rich sellion ph'd water which wouldnt be hard but ph changes dramatically so buy a ph meter/test kit and some ph up down

distilled water is 7.0 at any drug store

that's the theory, but it isn't always 7.0 in reality.

It's close enough to do until he gets some real calibration fluid.

yep and if your really lazy(my tap is on point) put an airstone in the water for an hour or 2 and ph it from that. my water is always 7.3 after 24 hours of bubbleing and it always come out at 6.8 i mean like to the dot.i know this doesnt apply everywhere but if you aerate the water for several hours the ph will balance out around 7.0 you will have to guestimate .2 or .3 up or down but it will work

Not necessarily. I've had distilled from the store as high as 7.6.
