Hello,
Can anybody explain why a bucket of tap water (nothing else in the bucket) has a pH of 7.2 initially, and then 24 hours later a pH of 7.4? The colour change in the test is quite considerable. I was going to place some natural slate I bought in the bucket to test if it raised the pH or not, before I put it into my tank. I don't know whether to do this now as the pH of the water has gone up on its own! I don't understand why.
Does natural slate raise pH?
Thanks for any help
