    I think that lowering the pH very slowly should also achieve the objective..... ie, dosing some acid.... I would suggest lemon juice, as vinegar MIGHT just cause cyano bacteria to bloom....

    Not to disagree, Jacques, But Kalk is safer. 3 weeks ago I had Alk of 20 dkh, dropped it to 8 within a week just by dosing kalk.

    What do you add to get it that high, the easiest solution is to stop adding it.

    The house of cards. Having such high Alk is not wise. It is not easy to sustain and when it goes wrong it is going hurt. IMO

    Just stop adding any buffers and it`ll come down on its own, probably within a week or so.
