SOIL PHing water

[simpleman]

I live on a well and my water that comes out my tap reads 7.8 on my PH pen. I want to lower it to 6.0ish and I read on Wikihow website that using pure white vinegar which has a PH of 2.6 will lower it. I was playing around and found that only a little bit is needed to bring it to the level I want. My question is if it is safe to use pure white vinegar or should I go and get some GH PH down? Thoughts please.

It's safe but from reading on here it's not very stable or permanent.

I use Earth Juice for raising/lowering PH.
