did add supplemental LEDs to my system maybe 3 weeks ago.A couple of hours after dark is a good time to look, they hang around under the monti, you haven't recently put led's on your tank have you? or upped the intensity?
it's a weak one only using it for extra viewing time. you could be right though. I took it down.mmm to me it looks like led burn hence me asking, it is more likely if the monti is under the led directly![]()
