Calcium reactor and Apex

[karl-rUK]

Hello all,

new to the site but not reefkeeping.
In the process of setting up a calcium reactor (reef octopus CR-140) trying to program my solenoid valve and there are a few conflicting programs I’ve seen on how to do this.

I thought I would have a second PH prob being (pH_Tan) as a back up if the ph drops below 6.90 then the Cal reactor will turn off.
Could someone Cast their eye over the coding I’ve done see if it’s ok and correct, needs bits adding to it or change g

many thanks

karl

The last statement is going to conflict with the first. Arguably I don't know enough about calcium reactors, but I did find this programming:

Fallback Off
If pH_Cal > 6.80 Then ON
If pH_Cal < 6.75 Then OFF

I don't think you need the backup pH_Tan.
