3 Channel LED light settings!!

Basically it is a combination of what you like the look of and what doesn't bleach your corals lol.

Typically you find a balance of blue to white you like, and slowly ramp up the brightness till your coral bleach then turn it back down a bit lol.

Generally speaking a 70/30 ratio of white to blue might be a good starting point, increase the blue for more florescence, increase the white to reduce a monochrome Windex look.

The moon light I don't know, depends what colour it is, you'll just have to try it, usually they aren't bright enough to make a visible difference with the main lights though. If it is noticeably bright, then again just adjust it to taste to start with.

Even when LEDs are dimmed, they are full power in bursts, that is why they bleach coral so easy so be careful. If possible, it might work better to leave the LEDs at as close to full power as possible, then adjust brightness by moving the fixture up and down.

All in all, the white channel is the main sorta wide spectrum light that will give you the growth, while the blue is added for looks for the most part.

Assuming the moonlight is white and of equal strength, the previous owner was running a 60/40 white/blue ratio which should give a result somewhere in the 14K to 20K spectrum, every light is a little different.
