Dosing Kalk with Apex (Programming Code)

[Electrobes]

Hey everyone, I just got the PM1 installed and the pH read outs are working just fine (After calibration), but I was to reassre I don't screw this up, especially since I am leary at how simple it looks...

Fallback OFF
If pHx4 > 8.30 Then OFF

Is the above code accurate? I want the doser to run 24/7, keeping the pH consistent (The tank is always stuck around 7.8-8.1) plus help boost the ALK and Calcium as lately the tank is on a growth surge. Is there anything I am missing? I plan on using the Outlet 8 (With a relay), if anyone was curious.

Thanks!

You will want to add

Fallback OFF
Set ON
If pHx4 > 8.30 Then OFF

Is this a reactor/stirrer? or a manually mixed container it will be dosing from?

Just a pre-mixed solution of Kalk, a kalk bin of solution. :)

Thanks jduck, I think I get it now. I receive my purchase on Friday, so here's hoping it works well! :D

One thing I added on my setup, was to program one of the feed cycles to keep the dosing pump off for a fixed amount of time before allowing it to go back to normal function. This allowed me to simply turn the feed mode on when I mixed a new batch, then it would be allowed to settle before running again, and I would not have to worry about forgetting to turn it off (to avoid pumping slurry into the tank), or back on (obviously stopping the dosing).

In my case I used Feed D for this, and this is my last line of the code: If FeedD 000 Then OFF
