Default 19 dKH Huh?

My KH was 19 when I tested it a week ago!! I was wondering if this was dangerous? I figured out how I got it there I was wondering how would be the safest way to lower it? I didn't think that water changes would be practical because most salt mixes KH's are so high to begin with. I have been keeping my Calcium up around 425ppm and was hoping to precipitate out the carbonate. After a week it dropped to 17dKH. Which I guess is a start. Is this something to even worry about or not?

Default Re: 19 dKH Huh?

I have always found this page helpful in determining my course of action. http://www.advancedaquarist.com/issues/nov2002/chem.htm
It uses the meq/L which is found by 1 meq/l = 2.8 dKH = 50 ppm CaCO3 roughly speaking.
Hope this helps.
Jim
