Lighting spectrum for 20 gallon reef tank

[Impala67]

I just bought a current orbit marine Bluetooth light and I have no clue on how to set up the light parameters. I really want to know what percentages of each light I need. Anything will help

There is a ton of info on here about lighting. The basic science is pretty simple. Most of the light corals need is in the blue spectrum. Beyond that, it's about your preference but increasing the output in other spectrum will potentially contribute to more algae.

I have the RedSea LED 50 and run it at 85% blue, 15% white. Everything is doing well.

What corals are you keeping?

What model of light? It looks like those lights are in the 20-30 watt range, which is really weak.

Sorry to keep you waiting lol I have Duncan, toadstool, zoas, mushroom, hairy mushroom, a BTA, and a RFA! I have set the light to mainly blues and 25% on red/green almost no white as it serves no purpose.
