Possible to switch off dosing pump via alk reading

[flat6guy]

Recently added the trident to my apex unit. I found that my tank was in need of dosing. Added a coral box dosing pump and have it programmed. What I need is a program for my apex to turn off the dosing pump outlet if the alk rises above 8.7. Is this possible and if so, how does it read? Thanks in advance

So I've figured out that I can use the alkalinity test results as a probe input. I've renamed the probe to Alk. Then set my min/max alarm range. From there I went to the doser outlet; 6. I used the advanced setup.
This is the program I've set up.

Fallback ON
Set ON
If Alk > 8.5 then off

Please let me know if this is correct or if I'm missing something. Thanks.
