Lights for a 180g

[sstwelder]

I'm currently building a 180g tank(72x24x24), I don't want to spend too much on lightning and was wondering if 3 AI prime HD would be sufficient to grow corals?

It would probably work for a softy dominant tank but you'd need to add more if you're interested in a mixed reef or SPS dominant system.

BRS has a number of videos covering light spread and depth penetration with regard to the par and spectrum. They even cover the Prime HD. You can search for it on YouTube.

Hope it helps.

Thanks for the info, looks like I'll either have to get 6 or 3 hydra.
