Good afternoon. Reaching out for help regarding lighting options for my 9 gallon Fluval flex. Looking to keep it simple and use a par 38 style bulb with a lamp and timer. looking for specifics regarding what spectrum of colors are best to use. Posting some examples of the various lights i'm looking into. open to suggestions. Thanks.
