I'm not asking y there's algae or wut I should do about it all I'm asking is how quickly will it begin to disappear with the absence of light don't need links don't need lectures or a short story and I kno my tank is healthy and established so no need to ask about it so if u don't have any experience in doing this as the original question asked then plz don't chime in and plz don't take this the wrong way just tryin to clear up the confusion that seems to be going on here lol
In my non-planted tanks...I only turn on the lights when I'm in the room and want to see the fish. Otherwise the fish don't care. In the wild they don't have a bright light shining down on them. The ambient room light is perfectly sufficient for them.

Without fairly regular lights that mimic the sun, that rhythm is thrown off balance and it stresses them. It's kind of like when a person fails to maintain a consistent sleep schedule and feels groggy and tired. The intensity of the lights are largely not important, but I don't think ambient room light ,is sufficient to create the rhythm.
