What is the schedule that you have set for the lights on your tanks?
For me, I have mine to slowly come on around 6:30 AM (right when everyone gets up so the living room lights don’t scare them with shadows) and then turn off fully around 6:30PM slowly (have them set where one out of the two light fixtures turns off and than 30mins later the other does to mimic the sun going down - similar to how I have it set when they first come on).
