Hi everyone! I just noticed this thread and decided to share my Jebao doser experiment. I used one for over a year and a half. Sadly, I had to decide to stop using it.
After only three months the unit decided to go haywire. Pump 1 of the three pump doser unit decided to start pumping continuously. It dumped the remaining part of my 5 liter KH canister. (about 4 liters) Of course, it did that while I was at work. When I came home I heard it squeaking and I could pull the power plug. (And start my doomsday-scenario water exchange. Only one coral lost.) Plugging the unit back in would make it go haywire again, as soon as the program tells it to dose something.
Upon contacting the reseller I was informed that it was a known issue with the software on the mainboard. They shipped me a replacement mainboard free of charge, guaranteeing that it had a new version of the software on it. After installing it, the doser seemed to work fine again.
Well "fine"... it just wasn't accurate. No two dosages were alike. I discovered that because my KH kept fluctuating. Not very noticable at first, but as the unit grew older, it began to fluctuate more and more. I first kept thinking it was my stressed corals that didn't have consistent uptake of the KH. Eventually, I started testing and re-testing on-and-on what my doser was supplying. A 1 minute dose of the same liquid and the same pump could easily vary up to 30% if I was unlucky! (Re)Calibrating obviously was of no use.
I slowly started saving up and searching for something different, thinking it would hold up until I found something better. I would just deal with the fluctuations... And then it dumped my full KH canister in the system again. That was 10 months after the first disaster.
After that I was fed up. I removed it from my system and started doing manual dosing while I waited for my new doser to arrive.
The new doser confirmed how inaccurate the Jebao was. Since installing and calibrating the Polish made "Doser One Evolution" both my KH and CA are rocksolid now for 3 months straight. The pump heads are of a very different kind and need to be lubricated. I absolutely love the solid build quality. And the price is good too.
Now this may seem like an anti-Jebao rant. But these are just my experiences. I am aware I may just have been unlucky? Or it may be my fault to be one of the first adopters? Or maybe it's my own fault, and my 240ml KH fluid per day is simply waaaayyy to much for such a unit? I'm just glad I finally have the solution that I sought.
