There is something I don't understand about 24/7 light too.

Under the sea, macroalgae don't need 24 hrs of sunlight, and in tank, why it turn asexual even when the light off for few hours.

Anyone care to explain?

Read in books by A. Calfo & E. Borneman, they advises to light refugium on a opposing timing as your main tank. Which means if your main tank lights off your Refugium will lights on.

This, they claim will prevent sudden drop of PH and oxygen levels in your systems.
