OK, I know this topic comes up from time to time, but I wondered whether anyone had any new ideas for autodosing liquid carbon; I have not seen anything satisfactory yet. I have a tank which I dose every day, but am looking for options when I leave it for a few days. The difficulty is in dosing only a few ml daily: it would be a lot easier if it could be diluted into a larger volume, but (as far as I am aware) it degrades when diluted. The only option I can come up with is a medical syringe driver which can slowly administer 20ml over a 2-3 days—fine for a weekend but no good for longer.
At the other extreme a micro pump connected to some airline could work, but I cannot find anything that would deliver less than several hundred ml while the timer switches the pump is on! Is there a middle ground that anyone has DIYed?
