Last time I had reef tanks either you had T5HO's overwriting the with Ice Cap ballast or Metal Halides with a chiller. I am torn between lights now, I am planning 50/50 Spa to Lps in a 90 gallon. So radions are out of the question I just can't justify $1500 for 2 lights. So next is Ai Hydras at $700 for 2 lights drawing roughly 180w total. Kessil360w's also at $700 for 2 lights but will need controller and draws roughly the same watts. What route should I go and would either or be enough lights for what I am looking for? Tank is 48×18×24 I think it's standard R/R 90 thanks in advance.
