I have heard from my LFS that you can use muratic acid which I would never do. Or dose seltzer water. It should help lower your KH, BUT( I like big buts) it will also lower your PH. Here is a link to an article. Good Luck References - Lowering the Carbonate Hardness

Start using the diy two part system.

I ended up taking my water to the LFS and he told me my Cal. was at 300 so i started dosing and now my Kh is at 12 and lowering. I havent checked my Mag since i started dosing, but it was at 1100. Ill test again tonight and post what i get. Thanks for your replies.

calcium and kh are opposites in a way... up goes up and one drops.. another way to lower alk i heard was vinegar.. dont quote me on that but i think some people use that with they're kalk reactors to balance the ph and alk.. or maybe it was just ph... i forgot..

correction: just looked it up and vinegar is used to lower ph.. but on the same thread the guy just dripped calcium and it lowered it...
