My fish tank is in my desk office / bedroom, and the LED lights from the controllers are very bright at night. I swear you could grow acropora under the blue light from my ATO controller...
Was looking at these from amazon? Anyone ever use anything similar or have another creative idea how to block the light while still be able to check the display?
The controllers in the picture are what I'm looking to dim. None of them have an option I could find to reduce the intensity.
