Hello
I'm looking at the Unipac Limpopo Black Sand to use as a cap on a dirt tank. While looking on here and online I've noticed a couple of people say that it HAS changed their tanks PH - one guy from 6.2 - 8.2. I'm in London and have high PH and will be using 50/50 RO/Tap and I don't want anything to raise the PH anymore?
All the product pages on Unipac Limpopo Black Sand say that it will NOT effect PH??
