This! FTW13 hours
nature sez
9 to 9 on my two Kessil A360X's over my 3 foot tank. 2.5 hour ramp up to a whopping 20/20 setting and 3.5 ramp down to zero with violet 40 and red 5 added for color. So six hours at 20/20. My LPS and Zoas are loving it. If I try to go higher, they complain. Them Kessils are mighty lights!I am doing at average what coral receve in real reef like in hawaii, around 8 and 9 hours full sun and 12h total daylight. So my radion run 12h and my t5 8h.
I do an hour ramp up then lights are on for 10 hours and then an hour ramp down so a total of 12 hoursSome of y'all have grumpy fish because they never get enough down time and the others have too much energy because they don't get enough day light! HA! When it comes to lighting your reef tank what is a good balance of time, on and off, for the fish and the coral? Let's talk about it!
1. How long do you run your lights on your reef tank?
2. How long do you think is too long for the lights to be on?

The ‘coralatic’ equation...not to be confused with the quadratic equation.I think more important than amount of time is the DLI. If can run 100% intensity for 8 hours or 50% intensity for 16 and the coral are getting the same amount of light. There’s probably a whole equation, I just don’t know it. At the equator days are roughly always 12 hrs, but other places they fluctuate more.
I guess Im getting at, I don’t think there’s a magic number that’s “too long”. I’ve heard of people with huge setups that stagger their lights so some lights are on 24 hrs a day to balance out the photosynthesis going on.
