| One thing to think about "growing" out also is macro algae.
Makes nice use of you sump space, throw some decent 6500k or so bulbs over them and give them some nutrients. Makes for good trade material at frag swaps or you can even sell it to people starting up fuges.
Chaetomorpha grows pretty fast in my experience. You can also try growing some other less available algaes like Ulva or some of the gracillaria.
Just some other stuff to think about doing if you are thinking about making this into a buisness in the future.
