Changing Colour of Output

Hi Guys,

I am using a longer version of the standard program and I want to know how to remove the yellow tinge in the morning and late afternoon.

It seems that i the morning from say 6am - 10pm the water looks very yellow and then again in the afternoon from say 5pm till 8pm..

Is this normal? I want to make sure I have the right lighting to grow good corraline algae in my tank.

Thanks again.

edit every dimming point - set the slider of the LEDs you don't want to 0% and save it
