stability. Less and you're more prone to variations in pH due to
downward influences (mopani driftwood, CO2 injection, etc). A higher kH

Uh yeah, ABOUT that. Mopani's influence is not to be believed. I have 1200
ppm water and dropped a small (small!) chunck into a tank with about 30
each of 2 rare species of snails - spotted nerites and porcupine snails.

Within a week the water was slightly amber and all the snails were dead.

Huh.
