Need help tuning my lights.

[nano_ryan]

Not sure how I should tune my lights for my 20g long. Its the Phlizon 165w black box. Its about 12 inches above the water surface. There is 2 dials that control blues and whites. Currently, im running blues at about 70% and reds,greens, soft whites and whites at 25%. Is this to high? What do you recommend?

It’s pretty much impossible to say without having a PAR meter to check the actual intensity in the aquarium where each of your corals is. Maybe someone with that fixture will chime in that can offer some more specific advice as far as settings go.

Blue/Violet at 70% is a good number.
White/red/green, add what looks good to you, I only use 5%.
The trick is to set and forget.
