Ultraviolet light will harm corals. Corals defense to this light is getting more colorful, but if you read back a few pages, I posted a link to an article where this theory was tested and they found no benefit to exposing corals to actual ultraviolet light (not to be confused with violet colored light). Take your UV sterilizer, remove the lamp, and put it over your tank and see what happens. It's not going to be beneficial.

A uv lamp was supposed to kill bacteria I thought? I never heard it was to help coral but to kill algae and disease bacteria in the water.

It kills pretty much anything that goes through the sterilizer. It's definitely not something you want to expose your livestock to. There aren't any LED fixtures with ultraviolet LEDs in them as far as I know. They just call them UV, but they are just violet.

That's what I thought, just wanted to make sure I don't misunderstand. True ultra violet kills, but these violet lights coming out aren't that. Any benefit of having a few of these or is it anther red/green gimmick??

There is something to do with the UV.
The most needed UV that bring out vibrant color of SPS/coral is around 380 to 390nm.
UVA is not that bad, it only gets bad when it is getting closer to UVB

Yes i was speaking of UVB as the one that can hurt corals. Is UVA the violet that we are talking about?

nope UVA is not violet. UVA is from 315nm to 400nm
Violet is range around 401nm to 420nm and purple is 421nm to about 430nm. These are not exact how it works, but its approx. neither violet nor purple are the UVA we hope we can get out of our fixtures

in most cases no, as their driver is not make to be able to interact with any controller out there.
