I recently upgraded from a biocube to a 90 gallon custom made tank. I have everything set up except the lights. I find that lighting is probably the most expensive part of reefing, and I was wondering what the cheapest type of lighting is that could cover a 5 foot long tank and be able to grow LPS and softies. I don't really care about customization, I just want corals to be able to grow under them. Any info you can provide is appreciated
