I have an Apex controller with a new Trident that I just got set up. My intention is to add a dosing system using the Bulk Reef Supply (BRS) 2 Part Doser Pumps. I'm pretty sure that I know how to program an outlet on the Apex to schedule the pump to turn on based on a time parameter (e.g. run for 1 minute every hour on the hour) which will be derived from how much dosing is needed. What I've never seen (or been able to figure out) so far though is to be able to program an outlet to actually take into account the tested values for Alk, Ca & Mg that the Trident is logging every few hours and then have it only turn on the pumps when those values are within a certain range.
For example, let's say under normal circumstances I've calculated that I need 100ml of liquid soda ash a day to keep my Alk around 10. That would translate to around 4ml an hour or around 4 minutes for a BRS pump. From what I've learned, I could program an outlet like this to accomplish that:
That works great if my load stays the same but what if it changes? The Apex "knows" what my Alk level is via the Trident, so how can I get it take that into account? In other words, I want it to only execute the above code (i.e. turn on the pump outlet for the specified time) if the Alk level is less than 10?
Note that I know how to do this with certain parameters like pH (e.g. If pH > 8.35 Then OFF) but how can I get it to do that with Alk, Ca & Mg? Does anyone have some example Apex outlet programming code where you've gotten it to work that way?
