For a few years I've been using 6 x 400W 14K SE Ushios to light my 500g sps dominant reeftank with very good results. Lately, I've been trying to add supplemental LED strip lighting for more 'pop' but have been unsuccessful due to the configuration of my pendants (long story). I'm wondering therefore, if I just swap out 3 of the current bulbs for 20K 400W Ushios, will I achieve anything near what I'm looking for or just an overall dull blue tank? Dimensions are 96x36x36, btw.
