Can someone help me with my dosing statement

I have the BRS dosing pump at 1.1mL per min.

Are these statements correct for dosing 4.4mL's every hour for a total of 7.5 hours = 33ml per day each.

For Ca:

Fallback OFF
OSC 000:00/004:00/059:00 Then ON
If Time 16:30 to 08:59 Then OFF

For Alk:

Fallback OFF
OSC 000:00/004:00/059:00 Then ON
If Time 05:00 to 21:30 Then OFF
If pH > 08.20 Then OFF

You might want to set the OSC to 056:00 then ON. Otherwise the subsequent dosing will be off by 3 mins.

Also 16:30 to 08:59 Then OFF, that leaves:

9AM
10AM
11AM
12PM
1PM
2PM
3PM
4PM

That's 8 dosing x 4.4/hr = 35.2mL. Leave it be or shorten it by an hour?

How's that look? My eyes are wigging out from calculating :lol2:

It just hit me, the pumps should be connected to outlets 4 & 8 on your EB8. Those particular outlets are relay outlets for low voltage devices such as your dosing pumps.
