It sounds like you have a pH buffer, not a pH test kit. A pH test kit doesn't alter your pH, it tests it. I believe that's why they call it what they do. That's certainly that case of our brand.
Ours retail for about £5.00, not £50.00, as do most of our competitors.
I thought £50 sounded a bit excessive for a bit of litmus paper :icon_lol:
