Desired KH level?

[Detritus Mulm]

I know that different plants do well at different Alkalinities, but is there an overall desired level for KH? From the little I've read, it seems that lower is better than higher?

My KH is around 8 BTW.

Re: Desired KH level?

5-6 or less is best for some species, most seem to do better in harder water.
But overall, a KH of 3 seems nice for any species.
