For now I will wait to see the results of me leaving the water out in a bucket for 24 hrs. Also, regarding going the natural route and having planted tanks, would low light plants in a low tech tank (heavily planted) have the same stability effect on the KH and pH?
Results so far:
Started at 4 PM, the pH was 8.8
8:30 PM the pH was 8.2
I will test again in a few hours before I go to bed.
