Lately, I've noticed that my torches, acan, and duncan (to a degree) have been shriveling up towards the end of the day, before the lights go off. Currently, I have my light (stock eHeim light for Aquastyle (https://www.amazon.com/EHEIM-Power-LED-Full-Spectrum/dp/B006G0C5R4)) set to be on from 11:00am to 8:00pm, or 9 hours. It gets a decent amount of morning light as well, but nothing intense or direct.

I'm wondering if I need to decrease the time period for the coral. I don't want to sacrifice display viewing time in the evening, but I also don't want to damage the corals if they are getting light exhaustion. Is that even a serious concern I should have? Should I maybe shift to 8 hours or less? Is there an ideal, universal time that tends to work well?

They get used to your light schedule and prepare early for the lights to go off. At least that's what I've always thought was happening. I notice a variety of my corals both soft and LPS do this. I wouldn't worry as long as they look healthy throughout the day.

That thought crossed my mind, but in the 20 months I've had my tank, I never noticed it before the last few weeks. Maybe I just don't pay close enough attention? My wife will tell you that that's not possible, but who knows.

It's a 9-gallon cube. It's been my intention to upgrade to something stronger and fancier, but the thing has worked and been chugging along, so I've left it alone. I would imagine I would see better growth with a stronger light.

The thing is surprisingly bright though.
