alk programming question

[Battlecorals]

I think I've got this down, but I am not 100% sure about which command will take priority. I am wondering if there's any conflict between the two commands, or will one override the other?

for example if my alk goes above the set point at 9.00 and turns the c02 off, will it come back on once the ph rises above that set point in this configuration? or will it stay off till the alk drops below 8.7

I guess I'm just not sure which order these should be in. Any guidance would be greatly appreciated.

I don't know much about the Apex software, but most programs execute line by line. So the second set with the alkalinity would cancel the first set. Better would be to nest the two together.

If alk<9 && alk>8.7 then
If pH>7 && pH<7.20 then
ON
Else
OFF

Not sure what that would be in apex speak, but that is what I would do.

Is this trident related or generic? Am wondering what you using to measure alk. And what is CArx?

thanks alot for the replies


I have the kh guardian, with the aim module hooked up to my apex

Had it set up to the apex a while now, just decided today try to actually use it as a control means. my motivation was more to have the c02 shut off if alk went above the set point, more as a back up fail safe of sorts, rather than actually control my calcium reactor if that makes sense CArx is my co2 solenoid

Thank you adam. Got it.
I also been using khg for 2 years now. Love it. They offer a special module for CArx byw you should check it out.
I never did that cause am using dastaco CArx.
