    Water changes. Strange that the pH and kH are high. Could be over dosage? What test kits are you using?

    The pH is high because the alkalinity is high.
    12 is actually not that bad if its stable and the pH is fine.
    What salt are you using? I use Red sea coral pro which is about 12dkh when I mix it.

    That fine, I was just saying sometimes the pH can be lifted by the alkalinity.
    I have experienced this, and someone explained it to me in fact it might have been @mytank
