uv filters

[kevol2004]

Hi, im new to the marine world, iv always had tropical fresh water tanks, and have used uv filters. My marine tank is well established now with corals growing etc, i dont currently have a uv on my tank but wanted to put one on it, however i think im over thinking and was worried if the uv would effect new or growing corals from developing. any information would be great thanks,
kevin
