Hi guys,

Can anybody tell me what the sequence is for the modes: A. Tidal Swell and B. Nutrient Export.

I am especially interested in the minimum speed % in the sequence as my WP25 shuts of at 20%.

I noticed that when I selected Nutrient transport the pump goes first through a pulsing sequence for an hour or so and then shuts down for a certain time. (I didn't time it).

If somewhere in the sequence the speed goes below 20%, is it possible for me to change that minimum speed?

Or do I need the whole code (modified with the minimum speed) in the "Custom code" section?

Hope you guys can help me out here.

The DCPump Class will always set the min speed to zero.
Here is where it is set in the libraries:
https://github.com/reefangel/Libraries/ ... l.cpp#L295
If you use the dimming channels directly and use the NutrientTransportMode() function, you can set the min speed, but there is also a bug identified by another user:

This is due to the fact that the function was reused from the vortech pump waveform and it uses 0% as a start of the parabola.
Doesn't the pump go back running when it goes past 20%?

Yes, it switches back on. I just noticed that it switches off once a while, so I assumed that the minimum speed is below 20% somewhere.

As for the link you sent me, do I need to paste those 4 lines in the custom code section and disable the internal memory use and change the "0" into 20 ?

Thanks in advance

No, it wouldn't work.
Just like the graph in the other post, you can see that the function goes to zero when the parabola starts.

Thanks Roberto.

Can you explain what a Tidal Swell does and what is the minimum speed% ?

Thanks in advance.

Tidal Swell is another mode with got from the Vortech pumps
