My tap water is full of chloramine and tests around 8.4 out of the faucet. I've been treating it with Amquel to remove all the ammonia and cholorine/chloramine and it seems to drop the pH closer to 7 after a day or two of bubbling. My latest grow is doing a lot better since I started the treatment. Distilled is a good option also, but over time you'll need to supplement with CalMag to make up for deficiencies in the water. But that's a task for another day once you test your runoff and get a full assessment of where you are. Hang in there, we'll do all we can to help get you a good harvest!
