Hi, I recently bought a UVC light on amazon to combat green water issues in my 55g. To clarify it is not a UV internal canister or anything like that; it is just a UVC blub that plugs into an outlet. I see conflicting information on this, but will it ruin my cycle. I placed it directly in my customized HOB. My HOB goes old (cycled) gravel > bio rings > filter floss > filter cartridge with carbon. I placed the UVC light directly under the filter floss, on top of the bio media. So will it ruin my cycle or not?
