Isn't THAT the perennial question!
You'll want to start watering with nute solution that is slightly elevated. I would not go above about 7.2, and definitely check your runoff numbers again in a couple waterings.
Most people growing plants will never have to woory about chloramine/chlorine; use it right out of the tap and it is fine. If you are concerned, google 'chloramine removal'. It requires activated charcoal, and can actually be done using a largish fish tank filter of the sort that you pack yourself with carbon and polyfill, and hang over the edge of your tank (bucket in this case) and run for a couple days to remove contaminants.

For pH up, use ONLY pH up designed for plants! The pool type is NOT safe for your green friends! Potassium hydroxide works; you don't need much at all.
stinkyattic Reviewed by stinkyattic on . First time, having problems Here is my situation: Closet setup, am using a HID florescent ballast for the growth phase then will switch to a HPS bulb for flowering. I have been running the florescent setup 24/7 for a little more than a month now. Plants are beginning to reach a foot tall. Started the seeds directly in standard "kegger" red cups which i cut holes in the bottom for drainage. I will be transplanting to a 6" pot once the plants start to show gender. (will also switch to HPS 12/12 at this point) Rating: 5
