Thank you so much Gandalf, you are wise as the name suggests. I definitely need to read up on the programming manual. Thanks for pointing me in the right direction and the link !!

Thanks fo the tip @Gandalf. Could you explain a little bit more ? If I understand correctly, I would need two ph probes ? and how can you assign a pump head two different sets of schedules ? I...

Thanks for the reply, Vinny. So it's possible to make it stop dosing if ph rise above set level. Is it possible to set a low ph limit and do double dosage if level falls below it ? Thanks

Hi,

Is there a way to make adjustments to the doser based on ph reading ? No i'm not using a calcium reactor and I do not want the ph reading to turn on/off a socket on the powerbar. Instead, I...
