Plants adapt, but if you do water changes, it drops back down so the KH is always moving...........and that's not stable.
I used Onyx sand for a long time, I liked it, but I never liked the KH issue.
I use Black flourite today which does not have that issue and is more aesthetic.

Oh ... so I guess I have to do away with the white sand I've right now. It's sad to tear up this tank, I'm quite pleased with how it looked after playing with some hardscape:
Is there any other way to pull this off? Thanks!
