Converting an eheim autofeeder to a liquidoser?
I have an extra eheim autofeeder that I dont use anymore and wondered how hard would it be to convert it to a liquidoser for ferts. From online shop pictures the electronic part is identical, but the chamber has some kind of tube that scoops 1ml of solution for release at a time - its difficult to make out any more details of the inside. Anyone have one and could explain or do a sketch for me?
Or does anyone use the autofeeder for dry ferts?
