Im not sure how old the power compacts that I have are because I bought the set up off of craigslist. I plan on having a mixed reef tank. I wasnt really looking to spend a lot of cash on this one because even though Im new to this hobby, i think im addicted. So most likely I would be upgrading to a much larger tank. But figured a nice lighting system for this one would allow me to start keeping some nicer sps corals now and would come in handy later as a secondary tank like a quarantine. So far it sounds like upgrading would be a good idea, any other comments?
