hi, how long do you keep your actinic lights on (the blue ones) i only keep mine on for 30 mins before my lights come on and again 30 mins when my lights go off at night, does anyone keep theirs on all day and is it benefical to the corals?

Yes, I leave mine on all day. They come on 1hr before lights and 1hr after lights go off.
I am not an expert, but this is what I was told:
Actinics are important for photosynthetic corals, most corals use the blue wavelength, due to this penetrating water the best. Therefore most corals need this light for photosynthesis.

I'm the same as grzy. I also find it's a good way to ease into the light, and to cool it down before turning on the moons.
Mine are on all day, with the daylights.

Mine are on from 8am to 8pm, the daylights are on from 10am to 3pm. Kinda like the brightest time of the day. Actinics are really important for most corals
