PH at 8.6 (How to lower without affecting dkh)

[magical26]

Hi all,

My parameters are:

1. Salinity = 1.024

2. Mag = 1380

3. Cal = 420

4. DKH = 8.6

5. PH = 8.6

Question is, how do i lower PH to about 8.3 without affecting dkh? I would like the rest of my parameters to be the same as before. Any suggestions would be greatly appreciated.

Will adding vinegar lower my dkh if my objective is to lower my PH just a little?

Will adding baking soda to raise my DKH to 9 further increase my PH?

Thanks

Using PH Test Pen. Calibrate using PH 7 solution. Check with LFS saltwater too, it read 8.2. So quite sure my PH is 8.6.
