To use a UV light or not?

[Mywifeisgunnakillme]

Okay that's good to know. I'll keep the UV spectrum on during the blackout. My zoas are fully open so they must be enjoying the light. Atleast I know some of my corals won't be fully disrupted for the black out period

If its true uv, you can see it, fyi.... manufacturers play fast and loose calling violet bulbs uv

You can tell its UV, picks up on all the green colours and makes them glow. Not the same as the violet spectrum the Ai Prime has

How do you know the corals are glowing because of true uv or just violet spectrum, just curious? The light is on, you can't see visual light, but the corals glow?

True UV does make some things florescent. I have a friend who collects uranium glass items, and they glow under UV light.

There is a touch of visual light, much less compared to the violet. and yes all the greenish hued corals glow very brightly. not as much as they do with the violet spectrum led
