So, I want to upgrade my light system after some recent internal debate. I have a 75g round corner glass tank. About 80lbs of live rock, and youre basic asst of beginner/intermediate corals. Mushrooms, button polyps, a few nems, some gsp. I want to keep some more adv corals like zoas and chalices and the like. What type of lighting setup should I look into, even a DIY where I gut the ballast I have now(since it matches the tank) and put new lights in that. I also dont want to skyrocket my electric bill current setup are t8s 4 bulb setup(2-24in, 2-36 inch)
