How to lower my KH?

[katfish50]

My KH is at 14dkh. All my corals and fish are fine. How can I lower
it? Isn't 12dkh the max one would want in a reef tank?

Stop using any buffers and begin doing small water changes until the ALK lowers to an acceptable level. The level should be arounf 10 to 12 dkh.

My PH was 8.0 yesterday so I added a PH 8.3 buffer and I have been adding this buffer at least once weekly and during my bi-weekly water change. Won't a low PH harm my fish? If I don't buffer what do I do to keep my PH up?

I have been having the same problem only I can't keep my PH up because my ALK was high. You will have that problem eventually if the ALK continues to stay high then all the buffer in the world will not raise your PH. My understanding is that the if the water used for changes is mixed corrected with salt and mixed with an air pump and air stone that the water will have the proper PH and ALk levels. This will help maintain the PH. Buffer can be used to help keep the PH up when the ALK levels have been brought down but you will have to do more regular water changes to keep the ALK levels under control.
I still haven't gotten my problem solved but I am gaining on it.
