    I'm dealing with a similar problem here, for the last two days.

    As I had a previous experience of this kind short time after buying my ProfiLux and I managed to solve it by increasing the water...

    Thanks for the reply, Carolin!

    It's strange, as for the rest of the time the pH probe seems to be working fine, so it's definitely plugged in the correct port. More than that, nobody has access...

    Well, the probe isn't faulty, at least in my case, as it's working just fine (or so I think) since the above mentioned alarm. It is weird indeed if a false alarm of the same type has been triggered...

    I think I understand what Matthias is saying: as long as the power supply unit of the pump is plugged in a functional power socket, even without any voltage input from the controller, the pump should...

    Puzzled by alarm message

    I'm far away from home and I got an alarm email from my ProfiLux. In the pH field it was written "pH 1 *** !"
    I know the exclamation mark means "alarm", but I don't understand what the three stars...

    Thanks, Matthias!

    I managed to manually program the pumps according to the generic rules of addition -- it isn't so difficult after all!

    Thank you for your clarification, Matthias!

    I was aware of the fact that the fish protection function is embedded in the pump (or at least Tunze says so), but I was wondering if the controller...

    Thank you for your very interesting input, Andy!

    I'm happy I'm not alone in this matter, but I don't understand why do you say "Tunze is correct". If you refer to the reply I got from them, they...

    Hmm... I'll try watching the pumps when idle while standing upside down! :D
    Thank you very much for the detailed explanation!

    Thank you for your reply, Antipodes! (btw, inspirational nickname for someone from NZ!!!)

    I imagine the pump can be stopped with enough force (it's nothing more than an electric motor after all),...

    Thank you for your input, mdanielse!

    Yes, I have my ProfiLux set to control the pumps according to the GHL directions, with the Umin and Umax mentioned by you.
    Good to know the plastic grids were...

    That's what they call "wishful thinking"... :)
    It seems the delay in dosing wasn't related to the feeding pause at all: during the next feeding pause one of the dosing pumps started doing its job as...
  13. Tunze 6055 & ProfiLux - NO fish protection function!

    I use two electronically controlled Tunze 6055 pumps in my display tank, which I control by means of a ProfiLux 3n computer 1-10V ports.
    Everything works fine in what concerns the control part....

    Dosing pump function rules, pls?

    Hi everybody!

    Although I bought my GHL dosing pump system a few months ago, together with a ProfiLux computer, I just installed it yesterday.
    After struggling for a couple of hours to program the...

    Erroneous pH Readings

    Well, I deleted the original post because the story was too long. To make it short, I had problems with the read pH values after re-calibration. I was puzzled by the fact that my GHL computer was...

    Oh, yes... that's exactly how I use it now. It's just two clicks on the PL View touchscreen, the same as depressing the feed# button. But there are only 4 maintenace routines to be programmed and I...

    Hi, Gunther!

    ... and thank you for your input!

    As long as I'm at home I want to see my fish feeding. Additionally, I have certain corals I have to feed individually by hand. This is why I have...

    Hello GHL!

    From my point of view, the PL Touch is pretty useless as it is now. A brilliant idea, a glamorous look, but almost no functionality at all! In other words, on one hand, if one intends...
