Re: KH

Hi Karen

Thanks for the response.  I accidentally mixed up a bag of gravel from a 
different source when I setup a new tank, and the bag contained some sea 
shells, all crushed up into little bits.  As a result, my normally soft 
water now has a KH of 8 and PH of 7 and this is with a constant flow of 
bottled co2 being pumped in.  I guess if I stopped the co2 the KH would go 
even higher.  Would you do anything else to lower the KH?  The plants are 
just starting to kick in and seem to be growing well except for the Bacopa 
Longifolia, which has put out new leaves, but they seem to be stunted.  The 
tank is about 3-4 weeks old.
