this is a T5 light shedule question

[HAPPY-REEF]

So I have a 24 t5 light Fixture with 4 slots and I'm using the ati 2 blue plus , Actinic, and coral plus.
How long should I keep each bulb on?
Also I plan on getting led bar if any situation on brand to get?

12 hours on. You could do a sunrise and sunset for one hour with just half the bulbs running as part of that 12 hours. This is for an established tank. If the tank is new, run only 8 hours and then after several weeks start to bump it up.

You only need 7-8 hours for the corals. No need to waste electricity or wear out bulbs faster. They won't grow faster with a longer light duration.

All on-- all off.........corals don't need nor care about dawn/dusk. That is just for a personal viewing preference.
