Changing light settings Fluval marine nano 3.0

[SunSill]

So I know that Fluval marine nano 3.0 20W is not the best light for reef tank. But in my case I have simple corals, so i think it should be good. Corals:
2x Ricordea
Green start polyp
Some mushroom
Stylophpora pistillata( sitting almost on the top of aquarium to get more light)
Blastomussa wellsi

i set lights and didnt change it for 2 months, but I understand that I dont want so much white spectrum. Before it was 20% right now 11%. Should i change it in few days/weeks or i cant drop white spectrum in once?
Thanks

Is any of your corals or anything else in your tank give you reason to believe your light settings need changing?

When I was running that light I had it almost maxed out. I think it’s only 30 watts

I just prefer lower white. For me it looks more "beautiful".

Fair!

Remember, we try to carry for livestock here You need to give your livestock what they need, that's the main priority here.

That being said, you'll be fine lowering the whites bit by bit but take it slow and monitor your corals response to the changes.
