I upgraded my 4-36" NO tubes to 2-72" VHOs (Icecap). I have 1- actinic white and 1-actinic for main lighting and I use two 36" actinic tubes for dawn/dusk. My question is should I replace the 72" actinic with an actinic white and leave the NO bulbs on along with the vho's?

My tank is FOWLR with inverts, mushrooms and zoos (some are not doing well, some great), and I was thinking of adding an open brain and/or candy cane coral. Will I need more light? The tank is 72X18X18.

Thanks

Can you fit all 6 bulbs in the hood? That's what I would do, put all 6 of them on. I have a similar hood except for a 75 gal and it will fit 6 vhos in the hood. So i would stagger the lights. For softies, URI does recommend a split number of Actinic White and Super Actinic Blue. For SPS or hard corals I would get 2 Actinic Whites and supplement that with your 36" actinic blues. Either way, I believe your corals will be happy with either choice. Also, with the Actinic White instead of the Super Actinic Blue, your tank will look a little whiter, with a slight less hint of blue. So then aesthetics come to play.
