water prep

[fishdaddy3]

it has been a long time since I started a tank from scratch and I can't remember how I prepped the start up water. I know that I used tap water, and this is what i'll be using this time around, but I tested the ph and it registered at a 6.5. (it was an old freshwater tester) What else should I be checking and how can I prepare the water for a reef tank.

everyting is plumbed, I just need to add water...i'm freakin' shaking cause I'm so close!!!!!!!!!!!!!
