Ok I ordered my new MH lighting and was wondering if for any reason that I should keep my Normal Output lights running in my tank? My MH is going to be a 20k XM bulb so I would not have actinic. Would it help me to run 2x15w NO Actinic 03 bulbs with the MH or would it just hurt things? I already have the 2x15w Actinic setup so it wouldn't cost me any extra to run em.
