Apex and calcium reactor

[calhounreef]

Hey everyone, I'm wanting to set up a calcium reactor on my apex with an electric solenoid and 2 ph probes, one probe for the reactor body and one probe to monitor tank ph. How would I code the apex to turn off if reactor ph drops too low and to also turn off if tank ph drops too low? Thanks in advance!

Good grief, finally got it figured out after reading through some apex forums.

If pH > 08.00 Then ON
If pH < 07.90 Then OFF
If ph2 > 06.60 Then ON
If ph2 < 06.45 Then OFF

For some reason I had to name the second probe with a lower case "h" on my apex display for it to take, kept throwing up an error message as "pH2"

after you get it running, you might want to keep an eye on it for a few days and do a few PH test to make sure the probe and the apex are all in sink.
it gets screwy sometimes which can spell trouble.

Wow, thank you I'll be sure and keep check on it. Screwy ph and a calcium reactor newby would probably be disastrous lol
