Thinking about starting this on my current tank. It is 180 gallon system with 40 gallon sump. Dosing would be daily. Right now the only feasible way to dose is by hand. Recommended dosage is .1 to .2 ml of Vodka per 25 gallons of water.

Eventually the dosage will go up and I approximate the final maintenance dosage will be in the 15-30 ml / day range.

Questions:

Can I automate this process with the Reef Angel?
Is there a set-up available for Reef Angel to dose 5-10ml at a time over a few minutes? Thinking to break-up the dosage into three increments, 8hrs apart.
Are the components compatible with a 20-80% Ethanol solution?

The RA dosing pump should be able to do it for you, but if you want 5-10ml over few minutes, then you will need a different doser.
The RA pumps doses about .75ml per second.

BTW, let me know how it goes.
My experience with dosing carbon source wasn't the greatest and would like to hear about yours since you have not done it before.
I started getting some bacterial white slime that was growing all over the place, especially inside my return pipe. I couldn't stop the return pump or when I started again, my display would end up full of the slime that was lodged inside the pipe and loosened up when I stopped the flow.

It would be cool to implement the recommended vodka dosing table into an automated program... Maybe when i get the dosing pump class working i can tack that on. In any case its a bit of work and not something i can do anytime soon. I'll start thinking about it though

Not that I do not want to buy the RA dosing pump, but any suggestions on which one would be available? Can you do a custom pump?

BTW I also have the 12V (DC?) IO module. Is there a 12VDC model I can run on the IO module or not enough current? Or I have some extra dimming ports can a DC pump be run on this or again not enough current?

Any takers on making a low volume dosing pump?

BRS 1.1ml/minute should be your best bet

So nothing should be done fast in a reef aquarium. Experimenting with vodka and vinegar dosing the last few months. This has been a great success for my tank. I have achieved 0 to near 0 readings on both nitrate and phosphate with little effect on the tank inhabitants and SPS corals.

Finally going to automate the process.

Will this code work? Can someone do a sanity check for me?

Vodka dose at 8 AM for 11 mins
Vinegar Dose when lights are on between 9AM and 9 PM. Dosed on the hour for 4 minutes
Will Mg dose later, ran out of money for dosing pump.

Will the standard dosing code handle an 11 minute dosing time?

Code: Select all
///Code to make Vodka Dosing Work one time a day
  ReefAngel.DosingPumpRepeat(Box1_Port6,0,1440,660);
//Turn on between 8 - 9 AM
  if (hour()>=8 && hour()<9) {
    ReefAngel.Relay.On(Box1_Port6);
  }else{
    ReefAngel.Relay.Off(Box1_Port6);
  }
///Code to make Vinegar Dosing Work
  ReefAngel.DosingPumpRepeat(Box1_Port8,0,60,240);
///Do not turn on Vinegar if lights are off
  if (hour()<=9 || hour()>21) {
    ReefAngel.Relay.Off(Box1_Port8);
  }
//Code to make Magnesium Dosing Work
//ReefAngel.DosingPumpRepeat(Box1_Port4,15,60,180);

Why are you turning on your vodka pump box1_port6 for the whole hour 8-9am? That will override the 11 minute once a day dosing you have right before that.

I want to turn it on at 8 AM and bolus dose the vodka for 11 minutes. How would I tell the DosingPumpRepeat to do the dose at 8AM? That was the only way I could figure it out.
