Filling in the 400-430 nm spectral range, add quite some PAR levels and helps with colors of corals (dont know that for sure, but red about it) - seems that corals build up colors on them in order to protect themselves from UVs.
I like to keep UVs as moon lights (but on very low range) - then will see some corals fluorescence in full beauty

I'm not sure what level to set the uv leds. Don't know if to much is bad. I have the light on a 38g IM tank. It's a mix reef with only a few sps frags. If you have a hydra 52 hd what would you recommend I run my levels at?

I dont have hydra but other leds. Start low with them and increase every week 5%. Looks almost invisible to human eye but blast a lot of power on corals. I have 3 times more uvs than whites and now I am at 20% after couple of weeks.
