    Curious what your doser schedules are like for core 7.

    Specifically I trying to figure out an easy way to manage my dosing over the entire 24 hour period (especially the alk components) with ease of management when updating dose amounts. The problem I'm encountering is how to maintain the min 5 min gap between solutions without really complicating things in terms of doser scheduling. If I set up my DOS doser to dose a specific amount over 24 hours and stagger the start times I'm concerned about either simultaneous dosing or insufficient rest time between solutions. Any ideas on how to manage this easily with the time gaps between solutions?

    I'm currently using 16 manual intervals as follows to ensure time gaps and no simultaneous dosing among the various solutions but this is getting really annoying to update regularly.

    In my setup I have the Fusion set up to dose 12 ml of each of the Core 7 supplements from the start time of 00:00 to the end time of 23:59. It is dosed directly into the return flow into the sump where it is very turbulent.

    I guess if you wanted to separate it by five minutes each you could stagger the individual start/stop times by 5 minutes as such,

    Dos 1, Start 00:00, Stop 23:44

    Dos 2, Start 00:05, Stop 23:49

    Dos 3, Start 00:10, Stop 23:54

    Dos 4, Start 00:15, Stop 23:59

    This should dose equal portions throughout the day. Then you can adjust the dosage quantity of each supplement without changing the schedule.

    I haven’t personally tried to do this, but I believe it should work. Good luck.

    Thanks for the idea.

    I've contemplated this but my concern is that even with the staggering there is a risk of overlapping doses if the stagger intervals coincides with the dose interval. So with the below dosing schedule for example, I would need to make sure my stagger time is towards the middle of the dose interval time I believe, otherwise the second dose of the first solution could dose at the exact same time (if i set the stagger to 17 minutes for example) as the first dose of the second solution starting 17 minutes later and so on.

    But then every time the dose amount changes so does the dosing interval and thus the required time of the stagger potentially. Am I thinking of this right?

    I'm contemplating the below schedule which would 100% prevent any simultaneous dosing and ensure gaps between solutions. By reducing the amount of intervals and expanding time of them this would cut my intervals by half and provide alk dosing every 3 hours which should be just fine. I just realized that by reordering the supplements that you can reduce the gap between alk dosing. I was dosing in order previously which groups the alk supplements and creates a larger time gap between alk dosing.

    Um, I might be losing something in translation so please bear with me. I’ve only used the easy setup Fusion controls and am not familiar with the one you have pasted. (May I ask what controller this is from?) But if I am reading this right you have your doses split up by 80 equal doses. Each dose equals .5 ml. with a pump speed of 7 ml/min. So

    7 (ml/min) divided by 60 (sec) = .11666 ml/sec.

    .5 (ml/dose) divided by .11666 (ml/sec) = 4.285 sec of dosing pump run time per dose.

    (I just started drinking my first cup of coffee so check my math)

    I know on mine, running only 12 ml/day, whenever it doses it’s only about a second at most. So, I think this approximately 4 seconds sounds right. If it is, I would think that simultaneous dosing would be unlikely to occur.

    I am curious, is there a reason why we should be staggering the doses?

    The first is detail from the interval summary shown below (the last is just an excel table I made). And yes, I concur with that math. They should not be dosed together or within 5 mins per Triton to avoid precipitation from the solutions interacting with one another. Mix a few drop of the solutions in a separate container and you will see why this shouldn't be done. So while yes, the run time is very short and simultaneous dosing is unlikely, the possibility remains if the wrong stagger is used (or more likely just the rest period would be impacted). I may just be too paranoid here, but when it comes to things like dosing that can take down a tank I don't like any room for error. Also, if the solutions are partially precipitating due to simultaneous dosing or too close of proximity to one another the required dose may be much higher than it otherwise would be.

    I've got you. It's a little complex to set up, but makes it super easy to adjust the dosing as you go. Note that I set up the quotes so that each quote is labeled with my outlet names. For outlets Triton2, Triton3A, and Triton3B, just change the Triton1 code to call the matching TriTimX timer.

    Now that is quite complicated but I see what's going on. I'll think about it more and see if I get the courage to give it a try. It makes me nervous using complex code with something like dosing that can nuke a tank with a mess up.

    But this is exactly what I was trying to figure out so thank you very much for sharing!!

    Thanks for the info on staggering the dosages. (Must have missed that detail) I noticed the precipitation when I was dosing into a low flow area but not in the high flow area. I'll go back and stagger my dosing times anyway just to be safe.

    When using this code can you see the scheduled dosing visually on the chart or only the small graph after the dose is complete? Thanks

    Future doses don't appear on the graph, so only the completed doses will be visible.

    Ooo I have been looking for this as well

    When someone gets the kahones to put this in let me know if it works

    I have mine go directly into my return pump so hopefully that high flow doesn’t precipitate to much as I just checked and they dose within seconds of each other been running it this way for awhile tho C033F8E4-2CC5-4CD2-B9FB-7C4E27E7B350.png

    Here is what I went with so I can have visual confirmation of scheduled doses and see the gaps. Results in about 30 doses of each solution per day with alk dosing every 3.5 hours by switching the order to 1, 3a, 2, 3b.

    So would that mean you dose 23 ml in each of those blocks? So you dose 46ml a day?

    Correct 46 total per day. The 23 ml is split over a 2.5 hour interval which doses 1.5 ml every 10 minutes.

    How big is your tank that’s a lot of fluid to dose

    What I don’t like about that is when your consumption goes up you then have to change two dosing intervals

    165g display / 200 gallons total. Yeah it is and most of my SPS is still in frag / small colony stage so I'm a little frightened for what the dose is going to be like when the tank is fully matured.

    Prior to the above change I was having to update 16 intervals which I've got down to 8 now (2 intervals x 4 solutions). I've been needing to update the dose about every 2-3 days to maintain my target alk.

    I've also notice running higher PH really increases the dose. I was running PH of 7.9 - 8.1 which increased over the past few weeks to about 8.1-8.3. This increase in PH added another 10 ml of Core 7 required to maintain 8 dkh. But that's all good since it translates to growth which I need right now. Once the corals are grown out I may drop the PH a bit to reduce consumption. I'm running a CO2 scrubber now to keep it higher.

    I’m dosing the same as u then I’m 23ml on a 100 gallons

    so 1.15 dkh a day is being consumed by our Corals
