So I bought this pump new maybe 2 months ago to dose Nopox. I have the schedule set to dose 1x at noon. Not long after setting it up, while doing maintenance, I noticed it wasn't dosing. (I'm aware of the issue with losing power to the Bluetooth model, and it wasn't due to this) So I had my gf set a timer on her phone and watch the doser each day- which seems counterproductive to having the doser in the first place. The schedule is set to run at 12, but on some days it will dose at 11:59. Other days it will dose at 12:01 or even 12:02. Today is a Saturday so I was able to watch the doser today. It didn't dose at all, which I guess makes sense. I've been dosing 5ml of nopox to my 50g system for 3 weeks now and have not seen the decrease in no3 that I was expecting. It seems to be staying between 10-20 ppm. Point being I'm almost certain it isn't dosing everyday based on my no3 levels. Has anyone else had an issue with this pump? I'm about to throw this thing in the trash and use the extra head on my bubble magus!!!
