DOS schedule adding pump defer

[JustSomeGuy]

So I finally have gotten to diving into my dosing program to try and increase my growth and keep things a little more solid. So instead of dosing alternating 12 hour programs between alk and calcium I made up another profile. I have alk dosing every hour on the hour for 25 minutes and cal every 30 on the hour for 25 minutes as well. I would like to add a defer time for when my return pump is off so I don't risk the 2 getting mixed. Here is my programming I am hoping I did this correctly.
I am still dialing in my dosing since I switched brands but right now with esv I am dosing 35ml and with this setup I went with a baseline 1ml each hour and 2ml during peak hours to simplify things.
I did make my schedule on Apex Fusion public under user justsumguy all are welcome to use it and tweak it.

I have alk dosing every hour on the hour for 25 minutes and cal every 30 on the hour for 25 minutes as well.

So, to make sure this is clear, let's take a sample hour:
00:00 - start defer of CAL
00:05 - start dose of CAL
00:30 - start defer of ALK
00:35 - end dose of CAL, start dose of ALK
01:00 - end dose of ALK, start defer of CAL

If I've got that right (and I may not...) then, I'd think you would want more separation between the two. I've read that at least 10min is good, though I think most setups could use less.

In terms of the programming, I think you'll want to move the Output check to the bottom. IIRC, the last instruction wins. So if an "ON" instruction (from a tdata line) comes after the OFF of the pump line, then the ON will win and the doser will kick on. This is really only a problem if the pump is off for >25min, though...

hope this helps. I attached 2 screen shots of what I am trying to do.
The reason only 5 minute delay between the 2 part is because of how small the doses are when 1 or 2ml get broken up in a 25 minute period. As for the reasoning for my 5 minute defer after my main pump is on was so that any residual in my return section gets blasted into the display to dilute even more. I would hate to have it off for any period of time in between dosing on both so this is kinda my failsafe. I do like to every once in a while direct feed the corals a nice slurry so I hold off on turning the return pump back on after the power heads have turned back on.
