I have a 75 gal 4 foot long tank I’m thinking of using A.I. prime hd lights how many would I need? I would to keep my opinions open as far as what I would be able keep. I’m thinking some sps maybe an anemone or hammer along with some zoas possibly even a clam. I know I can start off with two for low light corals but on the higher light needing corals how many do you guys think I would need. Thanks
