Macro in a display as a method of nutrient export isn't an option if you have algae eating fish. Especially if you have tangs. They will eat it faster than it can grow. And seeing as how this is a 110 gallon tank I'm sure a tang or two are a likely possibility. I'm not sure if there are any macros that tangs and other algae eaters won't touch.I grow macro in my display tank. you could do this as an option. This will not replace a good skimmer though.
