Hi everyone, lurker here and my first post, thought I could add my guide previously posted at the plantedtank here. It's an alternative to the other Auto Dosing Guide for the Jebao.
This guide has been tried on the Aquamedic Reefdoser 4.
It is basically the same doser as the Jebao Auto Dosing...
i found this while lurking around Hackaday if any one has any experience with Arduino maybe you can have a go at this, im considering it my self once i have cleared some of my other projects on the go
Here it is ARDUINO CONTROLLED DOSING PUMPS
