Ok. So it doesn't move at all when the lights are off, I work nights so my light cycle starts late so I can enjoy the tank when I'm off. I looks full wavy and happy when the tank is dark but as soon as the LEDs come on it's on the move. I know mags love strong light but I'm thinking and please correct me if I'm wrong since it was in a tank for 3yrs with T5s which has a much broader spread and now it's under LEDs with more of a direct light could it be the lights are ****ing it off? I had it originally at 80% blue and 60% white and then I cranked both up too 100% with no changes, meaning it's still moving. I'm at work now and the wife called to tell me it moved again and she put it back on it's rock. I'm running out of ideas so I told her to drop the whites to 40% and blues to 60% and see if it stays put. Since it doesn't move when the lights are off I think I can rule out flow issues and narrow it down to lighting.
