Yeah man, like I said before, you're over complicating it. Similar temp to the touch is fine, and don't worry about the ph. I keep a plastic cup with my water change bucket. Sometimes using a cup is easier than powering the bucket or siphoning the water in. Lower the bottom of the cup in first and slowly tilt it till your even with the waters surface, so you don't disturb your substrate.
