Re: Re: Vals & peat (was Gitte's Crypts)

Sorry about some misinformation given in the below post. I should have 
checked directly before posting, since I haven't tested kh and gh in several 
months. I just assumed it would be somewhat stable, at least out of the tap. 
I suppose a significant drop in pH should have clued me in? Anyway, I decided 
to do a check after posting this, and dKH was 1, dGH at 3, in the tank, and 
comes out of the tap at 2 dKH. Since I'm adding carbonates and bicarbonates 
to the tank (even just today), I'm a bit at a loss . . . but the bottom line 
is the same. The contortion valisnerias don't like the soft, acidic (with 
CO2) conditions.
