How many hours per day must we on the light then consider ok?

Meaning there must be a standard or basic number of hours we need to on the light in order for our live stock to survive.

it depends on the corals and type of lighting being used. there is no hard and fast rule to hours of lighting as every tank is different. type of coral, type of lighting and height of tank is important too.

i would suggest a minimum photo period of 10 hours if using T5s. for MH that is supplemented with T5, the T5s could be turned on for a few hours earlier in the day, then MH turned on during midday and offed during the evening, when the T5s come back on again. this is good if you want to simulate natural daylight hours and normal light fluctuations.

If using MH alone, lighting hours could be reduced.
