I bought the 13W 50/50's and the ballasts and hookups to go with them from ahsupply.com. Although bleeding blue advised me to purchase the $97.00 96W setup from hellolights.com, I don't trust a man who's reefs.org icon is a giant weiner in place of the washington monument. :roll: However, Mike did use these same lights in his tank, and, with the refugium that I am going to set up inside of the 10 Gallon tank, my nano will be smaller than his. Basically, according to Mike, and with this I will agree, Mike's tank is pretty freaking sick. 8) If he used 13's I will too. :twisted: Plus, now I can spend more deniro on corals and stuff.
