I just got a test kit from home depot and see that, much like my soils around my property, my well water is low in PH. It wasn't numbered but the color indicated border cautious. Since this is how I get my water (RO/DI) i was wondering should I do something to the water to bring it up before mixing or using it for top off. I use IO salt and it states the PH on it as good after mixed but I'm not sure. Thanks
