MY KH is to high

KH isn't something I use to check but now I'm spending more time on my tank, I went and got a lot more Test kits and one was the KH (carbonate hardness). I took 19 drops to turn it from the Blue to the Yellow, now I want to have my tank in the 7-12 drops zone so how do I reduce the KH?
Will water changes do it or is there another way?

What is the KH of your tapwater? RO water is the best way to go when reducing KH.

I've just changed 20ltrs of Tap water and will wait abit before I do my test again.
I'm due to change 50ltrs of Sea water on this friday so I guess that will help and I'll bring my water changes back to every week till I get it back down.
Does this sound like a good plan?
Also would "Purple Up" push the KH up as I was putting a cap in each day?

I got it down to 16 drops(KH 286.4ppm??) with the 20ltr tap water, will do the 50ltr saltwater tomorrow.
so should I aim for KH @ 200ppm?
