redracer77 Posted February 28, 2011 Report Share Posted February 28, 2011 I have recently setup a nano marine tank and have a few questions about lighting. I have 2 x 11PL lights 1x blue 1x 8000k White. Do I need a moon light? What time peroids should the lights be on for? Should the blue be on longer than the white?

suphew Posted February 28, 2011 Report Share Posted February 28, 2011 No you don't need a moon light, but it does look nice. You can leave the main light (white) for as little as about 8 hours or up to 12 or so hours, the days are long near the equator The blue light is mostly for looks only, I like to have my blues come on before I go to work so I can look at the tank, my main lights don't come on till hours later, I also have the blues on after so I can see the tank late in the evening Quote Link to comment Share on other sites More sharing options...
