Aerating or aging the water achieves just one thing - gases dissolved in the water come in balance with gases in atmosphere, the end result depends on your source water (what gasses and in what amount it had). This process usually alters water pH as well.
So, this will just tell you what is your real water pH under your normal conditions (not under pressure in pipes or underground). Just don't measure pH of your water right out of tap, it'll simply be wrong.
Be careful with peat moss - check it for fertilizers. They may be not listed in the ingredients but may be present. I got 8 ppm of ammonia in a water filtered through "100% pure Canadian organic peat moss" bought in Home Depot. Plus high level of nitrates and phosphates. And probably a lot more - I just didn't have tests for it.
