Hi Rob,
Indeed, i see what is confusing here.
1. I have a LED Light, that matches this one (found this in google using my reference - LED, 90cm, ZhongShan YF-LED1200A, 5-75W, IP67):

2. Before this LED Light there is a Digital dimmer: https://www.sera.de/nl/product/zoetwater...al-dimmer/
3. The power supply to this dimmer (and LED Light, as this is all connected inline): 12VDC/5A
When I was writing about the back off the controller, in my first post, this was the Digital dimmer, i see now that this was confusing
I do see a increase/decrease in light intensity between:
I also noticed that the light drops when the ATO pump kicks in.
I've bought a cheap power supply to powerup robotank-reefpi: https://nl.aliexpress.com/item/329072126...4c4dbG5yiX
Could that be the reason?
Kind regards,
Jimmy

I do see a increase/decrease in light intensity between:
- LED connected to reef-pi (manual set to 100%) (without digital dimmer)
- and
- LED connected directly to original power supply. (with digital dimmer) This illuminates the aquarium much beter.
I also noticed that the light drops when the ATO pump kicks in.

Could that be the reason?
- If yes, would it be an option to use the LED Power supply as power supply for robotank?
- If no, that i presume that best option is using the LED power supply as an external power, however i'm not comfortable with wiring, what do you mean with 'center positive'?
Kind regards,
Jimmy
