Apex shutting off dosing outlet.

[Jasonak]

Hi
I tried using advanced programing on my apex power outlet but couldnt get it right kept getting error messages.
So since I now have a newer apex running, I just switched the apex outlet to PH and did this.. will this keep outlet on unless it hits 8.4 im dosing Kalk and just want a failsafe.

Right now, you have it set to turn on when PH hits 7.0 and to continue dosing until it hits 8.4. PH shouldn’t drop that low
Here’s a thread of someone that has done the same thing, with some good recommendations. https://www.reef2reef.com/threads/help-with-ph-control-through-kalk-on-apex.482329/

So this did not work, my DOS just stayed off. Ive got the DOS its self setup to do what I want and its working fine. I just want a failsafe in case it goes on the fritz and starts dumping alk into my tank. Im doing a two part now instead of kalk.

Why not use advanced settings?

Set on
Fallback OFF
If PH > 8.4 then OFF
Defer 005:00 then ON

Thank you this will shut it off and then it will come back on once it drops below threshold again ?

Yes if ph is greater than 8.4 it will turn off. Then when it drops below 8.4 for at least 5 min outlet will turn back on. That is what the defer statement does so outlet is not flipping on and off over and over while ph is 8.3,8.4,8.3,8.4,8.3
