I am running 2 blue+ T5 for dawn simulation, 250w Radium for daylight hours, and Reefbrite XHO's for dusk. The problem is that the corals (IMO) only look good under the XHO's and that is very frustrating to me.
I am wanting to borrow it for a weekend so that I may see the effect on my corals in my tank. The A80 might be a better solution for me as they are cheaper and I'm not looking for PAR, just coloration - where are you located?
