Help programming dosing pump.

[Mgoesma]

I have 2 brs dosing pumps. They dose 1.1ml per min. I want to dose 30ml a day for each. I want to turn the pump off is ph is ever gets > 8.25. I want alk to be spaced out during the night (3:00 to 10:00 is my low ph time)and ca during the day.(maybe 16:00 to 23:00). Also please let me know if there are any other safty checks i need.

what would i have to add to make it so CA and ALK can not be running at the same time?

Use the offset for that on only one of the two. 0 minutes for one and 30 minutes for the other is best when only dosing 2 things.

If you use the non-overlapping time periods you mentioned in your first post, you don't need to do anything else.

This. Didn't look closely enough at the original post to see you wanted alk in the night and Ca during the day. If you were spreading over 24 hours, you would use the offset.
