Hi guys I'm in the process of setting up my first nano reef tank. My question is about lighting for a softie setup aimed at beginner coral like zoanthids, acans etc . I have purchased two non-dimmable E27 led bulbs. They are rated at 12w each. They each have two blue 450nm-460nm and two uv 390nm - 405nm leds. My question is whether the uv would be too much and harm the corals? Thanks in advance

Not familiar with that bulb but at such a low output you should be fine, 390-405 is just in the visible range it may help improve photosynthesis and make your corals fluoresce more.
