So I've run out of my drop checker solution.
Is the below correct?

Is the below correct?
- Add 6g of sodium bicarbonate (NaHCO3) to 500ml RO = 500ml of 400dKH solution.
- Then dilute 5ml of 400dkh solution with 495ml H20 to get 500ml of 4dKH solution?
- Take 5ml of this into drop checker and add 5 drops of my AP PH test kit?
- is the above correct?
- if I wanted more than 5ml of the 4dkh solution in my drop check i.e. 5ml, would I need to add another 5 drops of the API PH tester?
- if you add more than 5 drops of the API PH tester will it give an incorrect reading or will it just make the colour darker?
