hi all, i'm wondering if putting a UV lamp over a pond is dangerous for koi? My pond has a bridge crossing it, and I plan to put a UV lamp under it. No fish can go under the bridge since it has nettings to prevent them from going from one side to the other, but the fishes might be able to see/get penetrated by the ray... Is this harmful?
