Question on lighting
I have just started my first reef tank I am using a Landen 16 x 16 cube but I am using a light from a 13 gallon fluval evo tank. Just wondering how I would go about using that light for coral growth. It has a white and blue mode and a blue mode. The catch is that it is only manual touch. If I put it on a timer it will only go to the white and blue mode.
