Probably not that Hard

[fio1022]

I'm trying to figure this out and its making my head hurt ...
I have 4mp40's on my aquarium.call them pump 1,2,3&4.
I have two profiles-nutrient export and random lagoon.
What i would like to do is have nutrient export on for 12hrs then random lagoon on for 12hrs.
Here's where im stumped.
I'd like to have
pumps 1 & 2 on for 72 min then
Pumps 3&4 on for 72 min then
Pumps 1&4 on for 72 min then
Pumps 2&4 on for 72 min then
Pumps 1,2,3,4 on for 72 min
Then repeat.
I've never used osc command before .
not sure how do this and keep everything synced.
Thanks in advance.

I haven't done all the math to confirm this is completely what you want but it should be close. You will need 1 virtual outlet to control the time when all pumps are on at the same time.

1:
OSC 000:00/072:00/072:00 Then ON
If Outlet virtual = ON then ON

2:
OSC 000:00/072:00/142:00 Then ON
If Outlet virtual = ON then ON

3:
OSC 072:00/072:00/142:00 Then ON
If Outlet virtual = ON then ON

4:
OSC 072:00/216:00/000:00 Then ON
If Outlet virtual = ON then ON

Virtual
OSC 288:00/072:00/000:00 Then ON

I'm sorry,still very confused...
Does the 'On' at end of OSC turn on current profile?
Still stumped on how to get all pumps on then repeat cycle.

Pump1
Fallback Night
Set Night
If Time 00:00 to 12:00 Then Lagoon
If Time 12:00 to 24:00 Then Nutrient
OSC 000/072/072 Then ON

If FeedA 010 Then Slow

Pump2
Fallback Night
Set Night
If Time 00:00 to 12:00 Then Lagoon
If Time 12:00 to 24:00 Then Nutrient
OSC 000/072/142 Then ON

If FeedA 010 Then Slow

Pump3
Fallback Night
Set Night
If Time 00:00 to 12:00 Then Lagoon
If Time 12:00 to 24:00 Then Nutrient

Pump4
Fallback Night
Set Night
If Time 00:00 to 12:00 Then Lagoon
