I'd never heard of using kH as a spawning trigger, as I've had the
impression that fish do not react to it directly. As to why we did it,
it was to spawn a new type of fish and tell the tale )

I never thought to track general hardness, I wonder if alkalinity change
(baking soda) affected gh, I know my tds definitely went up. My main
experiment was to see how changing levels of KH and the affected pH,
would affect a heavily planted community tank.

Hmm.. I think I see another experiment coming on
