ALK raises PH. If you have a doser, instead of dose once a day, you dose every three hours small amounts. Make sure you do the same with CA. My doser starts at 12am/3am/6am....... And it goes...... It doses for 8min. Not sure how many ml. Dose CA 30min after. 12:30/3:30...... Make sure you dont dose the same amount as you dose once a day. Brake that in a 24hrs period. Let me know if you understood.
