    Dosing with aqualifter for 1 minute

    Still a bit new to apex.I want to dose 9 times a day for 1 minute each using Aqualifter.Would this work...

    Fallback Off
    If Time 00:00 to 00:01 Then On
    If Time 02:00 to 02:01 Then On
    If Time 04:00 to 04:01 Then On
    ...etc
    Defer 00:01 Then On

    If I want to add a pH clause
    Would it just be...
    If pH > 8.3 Then Off

    DO I need a Set Off in there to make sure its off?

    You want this

    Fallback OFF
    OSC 000:00/001:00/159:00 Then ON
    If pH > 8.3 Then OFF
    Min Time 001:00 Then OFF

    I finally read the OSC for dummies and feel like I understand that better.
    If I put words to your OSC, it reads: there is no initial on time, then there is a run time of 1 min, then it is off for 159 minutes. It loops like that forever in a 24 hour ( 1,440 min cycle), except when pH is abve 8.3.
    Is that a good description?
    Why do you need the Min Time 001:00 Then Off?

    If I wanted to get very exact in the time it runs to micro tune it, could I do this?

    Fallback OFF
    OSC 000:00/001:05/158:55 Then ON
    If pH > 8.3 Then OFF
    Min Time 001:00 Then OFF

    Yes.

    The reason for the min time is so that if the pH gets above 8.3, it just skips the rest of that dose and can't short cycle.

    All worked well, but I am wondering about only dosing at night.
    Is it basically just limiting the run time to 12 hours and increasing run time by 2?
    Also, I changed it to 24 cycles of 1 min
    Would this work....

    Fallback OFF
    If Time is 00:00 to 12:00 Then OSC 000:00/002:00/058:00
    If pH > 8.3 Then OFF
    Min Time 002:00 Then OFF

    No, it will not work. You cannot just string together commands like that. You need to use the If Time statement to hold the outlet OFF during the period you do not want the OSC to operate.


    Fallback OFF
    OSC 000:00/002:00/058:00
    If pH > 8.3 Then OFF
    If Time is XX:00 to YY:59 Then OFF
    Min Time 002:00 Then OFF

    Modify the times XX:00 and YY:00 as needed.
    I'm not a Neptune support rep. Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    I have seen reduction in growth not an increase when dosing 12 hours vs 24. This is because in both my experience and in my research, KH stability has a higher effect on coral growth and health than pH stability (as long as you remain within the range of 7.8 to 8.4). If you want to try it out to see the effects for yourself, you need to do this (this will give 9 minutes of dosing over 12 hours).

    Fallback OFF
    OSC 000:00/000:45/057:20 Then ON
    If Time 12:00 to 23:59 Then OFF
    If pH > 8.3 Then OFF
    Min Time 001:00 Then OFF

    Is your probe accurately calibrated? Unless your alk is well below NSW levels, you dose significant levels of ALK through a calcium reactor, or have CO2 levels in your home that are verging on dangerous to your health, then your tank pH is at least 0.2 above that.

    Alk 8.3
    Scripps NSW is 8.0
    I checked with another reefer and was a 8.0
    But I will recalibrate again
