Re: [APD] Water Hardness and PH

[Rushui Guan <bosemani at gmail_com>]

I did a test, where I put as much Seachem's Malawi/Victoria Buffer as
I can in to a small amount of water.  It turns out that Seachem's
Malawi/Victoria Buffer only effect KH, and doesn't increase GH at all.
 Plus my tab water only has a GH of 2.

mystery solved...
