Apex Program Help

[Luke Schnabel]

I currently have my Apex dosing 750ml of Kalk a day all day but I would like to separate that into two different doses at varying rates and add a bit more to the total dose. Hopefully getting my pH swings a little less by dosing more at night vs steady all day.

I need code for this:

Using BRS 1.1ml Doser
I would like 250ml to be dosed between 11 am and 10 pm
I would then like 650 ml to be dosed between 10 pm and 11 am
pH Greater than 8.45 OFF
Fallback OFF

You shouldn't need to write a program I just setup my dos and added different interval's for which I dose, for example at night I am dosing 400 ml, then I stop at I think 9:00 am for about 5 hours then I start dosing again at 2:00 but doing 600 ml. I am using the fusion app to setup very easy.

The BRS 1.1ml pump isn’t as smart as a dose. I know there is code that is probably 3 -4 lines but I can’t get it to change the dose for certain hours.

sorry missed that part of it. Not sure then.

Can I stack this OSC code? It has no set time as off though?

Fallback OFF
OSC 010:00/018:11/031:49 Then ON
OSC 010:00/032:28/017:32 Then ON
If pH > 8.40 Then OFF

I’m pretty sure you can only have one single osc statement in any given outlet. I think you could setup two virtual outlets, name one Dose250 and the other Dose650. put the corresponding osc statement in each virtual outlet and then program the physical outlet to turn on if either virtual outlet is on. Never trust what comes out of my mouth though!

edit. Oh yeah, forgot….you would need to add an if time xxx to xxx then off at the end of each of those virtual outlets. Otherwise they’ll just continually cycle

actually that sounds solid too me

Make sure to check the actual output of the 1.1ml doser. I have 4 and they are all 1.9 or 2ml/minute

I was going to suggest running into a container first to make sure what your really dosing

Along the same thing mentioned with the virtual outlets. You might be able to do it with just the pump outlet using a couple of if time xxx if you know the pump rate to iron out the dosing times


Set OFF
If Time 6:00 to 8:00 Then On
If Time 18:00 to 23:00 Then On

Problem is they want to dose totally different amounts during the day vs night. So for this to work they have to use one osc statement but change the amount of hours of dosing to make the difference, creating a gap in dosing which is what it sounds like they are trying to avoid. That said, it’s most likely much simpler to do this way, it just wouldn’t be perfectly spaced intervals, continuously.

Thanks for all the recommendations. But yes, I am trying to get it to dose more at night than the day using the same pump and same outlet. I can try the virtual outlet thing this weekend and see if that solves it. I may have to get a bigger pump as well because looking at how much I want to dose the pump will be running nearly 70% of the time at night.
