I have a question about distilled water.
I read that using distilled water and then adding shrimp minerals to it to bring the minerals back up is a good way to lower the PH.
So I went out and bought bottled distilled water. I tested it, and the ph was 6.0. I added the minerals and then let it sit for 1 hr. I tested the water again. The GH was at the high end for cherries, and the PH was about 8.2. I figured I added too much minerals.
I had another bottle of of distilled water. I tested it when I opened that one. It was 6.0. I added the minerals. Only a little dash. I let it sit. 1 hour latter, tested the water. Barely a trace of gh and kh but the ph was 8.0.
So, my question is. Does the ph of bottle still water go up after you open it and then come back down? Do I have to leave it sit before it comes down?
Thank you very much for any help you may have to offer.
