I have got one light in my cichlid tank which is for planted aquariums and I am looking to fit another one. But I want one that will help show up more colours. I thought about marine white but for a reason I can't remember my LFS didn't think it was a good idea. He said I would be better off with a blue tube to show off the blues and yellows but fitting this would actualy make my tank look duller. Just looking for some suggestions or opinions on which is best.
