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

[glb]

I finally hooked up my doser for alk. This is the Program I wrote for it:

I want it to come on at 6pm, stay on for one minute, then go off. I also want it to turn off if the ph gets to 8.35. I saw some code online that started with OSC but I have no clue what it means or if I need it. The doser is plugged into one of the 4 outlets of the Apex, Jr., which is the right kind of outlet. Did I do this right? Any help is greatly appreciated!

So you get 1.1 ml of alk, also have you tried to see if the addtion of your suplement triggers your ph probe due to proximity ?

I moved the ph probe so it’s “behind” the pump in the flow direction. It’s in the 1st part of the sump and the dosing will be in the second. Is that what you meant?

Yep so then you just need to know how much alk to does and then break it into different times so you keep it even all day.

It says my time is illegal. I’m going to look it up in the manual.

So even though it’s a small amount (1.1ml for a 40g) I still need to break it up? I was thinking all in the evening to keep the ph up at night. Am I thinking about it wrong?

Are you sure your doser puts out exactly 1.1ml? I have 3 of the dosers and all 3 are different. After you find out how much you need to dose daily, use THIS calculator to do the programming.

So I left out colons in the time so that’s fixed. But I just realized that the code I wrote will actually make it run for almost two minutes. It will read “on” until 18:01:59. How can I get it to only run for one minute? I tried doing “if time 18:00 then on” on one line and “if time 18:01 then off” on the next line but I got an error message. I’m only dosing 1.1ml daily right now and the code only works in minute increments. If I wrote “if time 18:00 to 18:00 then on” would that work?

Thanks! I tried it but it won’t let me enter any amount lower than 2ml. Can I work around that?

When I only needed 1-minute I couldn't figure it out either. Like you said, it's actually 2-minutes.

Honestly if that's all you are dosing daily, I'd manually dose it

Well, I have it installed so I want to use it. Lol. I hate manual dosing. I just need to figure out the code

Try:

Fallback OFF
OSC 000:00/000:05/119:55 Then ON
If pH > 8.35 Then OFF


not 100% sure, maybe someone else can chime in
used https://www.reeftronics.net/adpg/dosingcalc.php
entered 2.2 ml total for the day then doubled the wait time between doses
that should dose for 5 seconds every 2 hours

I think I can use the OSC code and have it dose half every 12 hours.

Fallback OFF
If Time 18:00 to 18:01 Then ON
If PH > 8.35 Then OFF

Should work

This will be the answer to all your woes!
Works great

Just put in your parameters and then copy and paste.

That's the same link I posted up above, great calculator

That’s what I had, but it will really run for 1 minute and 59 seconds. From 18:00:00 to 18:01:59.

It is, but it’s not working for the amount I want to dose. You have to put in at least 2ml.

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

So if I dose .6ml twice a day (yes I know that’s 1.2 total but that’s ok) can I write an osc code?
