I have a 20 gal
tall. Coral and CUC only. I currently have 2 Marineland Reef Capable lighting fixtures (White & Blue) for "Daylight" hours. I have 2 Stunner strips (445 nm blue) and 2 Stunner strips (magenta/453 nm Blue) for "dawn & dusk".
My question is:
Can I get away with using only 1 of the Marineland fixtures? Daylight and dusk/dawn are on timers, but the marinelands are set to white/blue. For blue only, I would need to manually flip the switches.
I don't wish to hurt my corals by blasting them with light or starving them for it.
