Too bad you are not a big DIYer, that second tank would be a good one to try lighting with all LEDs. They had a tank at MACNA that was a 2 1/2 lit with 6 LEDs that looked pretty good but they said they just set it up and had no idea how well it would do in the long run. They used a heat sink from an Icecap ballast to serve as the hood and mounted the LEDs on the bottom.
