Controlled Dosing with Trident is All Over the Place

[Scott Christenson]

I have Apex with the DOS and the Trident. I went through the Task for Controlled Dosing and set the alk to 8.6. It adds alk just fine but does not stop when it hits 8.6, now I'm up to 9.48. What did I do wrong?

Could it be that you're percentage of which the trident can manipulate the dosing is too high?

You can also go into the advanced window of the programming and set another line of code that would say something like:

If Alk > 9.0 then off

That would allow you to have another level of redundancy built in to your programming for the dosing of alk and calcium (if you would add a line of code to calcium level as well).

So I read the summary as that it should not go above 9 for alk, but now I'm at 9.48.

Once you get above 9, it defaults to your standard dose, which seems to be 8ml

So lower the standard dose then?

Yes. Trident 101 is to first stabilize parameters using regular dosing. Once you know your demand, you set that as the standard. It is a protection feature to avoid over or under dosing significantly.
