Looking for some advice in best use of UV lighting for this system? When should I have my pink/cyan/blue/purple/cold white start stop and what percentage. Just set tank up today so no frags or corals in tank yet but want to get it set up and ready for when I can add. I don’t want to mess with the lights 100 times. Would like to get it set and leave it since it’s programable. Any help is appreciated...

Welcome to Reef2Reef!

I'm not completely familiar with your led fixture. But I believe is not very powerful. But knowing how deep your tank is would be helpful?

Most important to your corals, when you add them, will be the blue spectrum leds. You'll probably be running those near 100% (depending on how deep your tank is). The whites are 2nd mot important and you'll run those anywhwere for 25% to 75% of whatever power you run the blues. All the other colors have far less leds and are FAR less important to the health of your tank. You can run those at whatever power levels you want to get the look you want in the tank.

Does your fixture have real UV? What wavelength are they? Some makers call 420nm leds UV when they are really violet. The UV range starts at 400nm and lower and you wouldn't see the light. And most makers don't use true UV because they don't last nearly as long as all the others. If yours are 400nm or higher, just consider them as part of the blue spectrum and run them at about 50% of the less of the blues. And I'm assuming there are very few of these 'UV' leds in your fixture?
