So I bought my Fluval flex 32.5 about a year and a half ago. I want to say it came with the Fluval marine 3 lights at the time but I’m unsure at the moment. My tank is a mixed tank with lps and softies. Anyway I’m not seeing super good growth and I was thinking of making the jump to at least on AI prime 16 HD, but I was wondering do I need to? Will one prime work for a 32.5 in width tank? I’m always willing to put money into my tank.
