Hey, my tap water is pH 7.4, kh 8, gh 15.
I have one tank I've recently started which I use 50/50 RO/Tap.
The kH and gH halve as expected to 4 and 7-8 respectively, but the pH stays at 7.4
What could be causing this buffering effect? Surely diluting to 50/50 with RO water should have an effect on this?
Any water chemistry experts who can explain what is going on here? Techy explanations are welcome, I was an analytical chemist many many moons ago so should be able to follow.
