You can, most folks run a reverse cycle to prevent a pH swing in there tanks during the night when corals and their zooxanthellae aren't using any CO2. Running it 24/7 might lower your nitrate and phosphate levels significantly and you might see some upset corals as a result.

Edge of leaves look serrated, so I think serrulata. I’ve always lit my refugium 24 hrs. Nitrates stay low, phosphates are 10.
