Lighting question

[Murice]

Hey guys I'm a little confused on the light situation... during day I run blue and white... at night do I turn both off for total darkness or leave blue on? I run refugium at night... do I run blue or white or both

Turn both off at night. Some people will run Blues like moon light. I prefer off and dark. On refugium you don't need anything fancy. You can run WHT, BLU, even RED.

Corals need darkness as well as light. Dark periods allow them to rest as in nature.
