Hi MASA, Possibly dumb question Friday for me... but I have 5k and want to improve my lighting if possible. Been using odyssea 2x54w with ATI bulbs 20cm above water line & I took a Beamswork 4500 72w(1w diodes) and changed most of the cool whites, to blue(450nm) and 4 green(510m I think), 2 red (600nm range). Tank is 1500x500x500. Mixed reef, 8 sps, 12 lps and 7 softies. What do u think I can get for 5k now? Maybe can sell my existing lights to add on?
