Is this good apex code for a BRS 1.1ml/minute doser for alk?

[glb]

Ahh ok ..I'm not the best with Apex code
Try If Time 18:00 to 18:00:59 Then ON

Ok I’ll try it.

So, I have to ask, if all you need to dose is 1.1ml, why dose at all?

 

[glb]

Ok I’ll try it.

Ok I did “if time 18:00:00 to 18:01:00 then on” and it took it. It will run for 60 seconds right?

Because it keeps the alk stable and helps with ph, which tends to be low. I’ll probably end up dosing 1.4 but wanted to start with 1.1 because the code is easier. I’ll adjust it up once I see what the alk does.

Your BRS deser may not be exactly 1.1, if you're trying to get that specific you may want to test that.

Oh, lol. I’ll test it now

So glad I checked! It doses 1.9/minute.

Yeah exactly, I have two of their dosers and I think one is 1.5 and the other 1.4.

 

[glb]

So I did the calculations and I wrote this to get it to run for 44 seconds (for 1.4ml)

 

[glb]

Apex accepted the code but when I went back to it the seconds weren’t showing anymore:

Will it still run for only 44 seconds?

If it doesnt display seconds I assume it wont use that field. That's a shame as mine gets here in a few days and I would love to use seconds.

Test it with RO

if you want 2 times a day then use


Fallback OFF
OSC 000:00/000:30/719:30 Then ON
If pH > 8.35 Then OFF

OSC 000:00/000:30/719:30 Then ON
If pH > 8.35 Then OFF

I'd like to use the OSC code, can you explain what the "000:00/000:30/719:30" is saying? I can't figure out how it comes up wit the 719:30

Thanks! Can you explain what the 3 numbers mean?

The first section MMM:SS is the initial time off command in minutes and seconds.
The second section MMM:SS is the time the pump will run in minutes and seconds.
The third section MMM:SS is the second time off again in minutes and seconds.

The third section MMM:SS is the second time off again in minutes and seconds.

How do you tell it what time (of the day) it’s going to run? I understand the 30 second run time but don’t understand why the initial time off is zeros and the third number starts with 719. Maybe I’m just slow, but I don’t get it.

 

[glb]

Ok now I get the 719:30. It’s 12 hours (720 minutes) minus the 30 seconds the pump will run. But how do you tell it when to run? For example, say I want to run it at 7am and 7pm? Or say I want to run it twice at night, like 9pm and 5am? I think you can program it to be off before 9pm and after 5am with a time code.

Here, use this calculator to program your dosing pump. Just enter in the info and it spits out the code. Copy and paste.

Thanks. I figured out how to use it for amounts less than 2ml, like mine. I calculate the time on, or the middle number, manually. You have to put in 2ml for the formula to work. So I take out the middle number based on 2ml dosing and replace it with the manual number for the actual amount I dose (1.4ml). The rest of the formula should be fine. I’m going to program it tonight and try it out. I’ll let everyone know what happens. Thanks again!

The first number is the minutes and seconds from top top of the hour. So if your code said:
OSC 030:00/000:45/029:15 Then ON
the doser would start on the 30 min mark, rum for 45 sec and then off for 29:15 and then off for 30 more minutes to get to the bottom of the hour. Now if you only want to dose at night you could add a second line:
IF Time 08:00 to 20:00 then OFF
So you would only dose between 20:01 and 07:59.
Try the calculator it’s fantastic or fusion.community. Great people there too for all your programming needs
