Great tank build! I just got back from MACNA and LED lighting was my goal. Acan and Orpheck were the best there. After playing with all the others I kept going back to these 2. The Orpheck had the highest PAR of all at the show, but the Acan was the easiest to use. The rep at acan suggested a few smaller units over a long tank instead of the longer ones; could adjust height as needed for particular coral placement. Just a thought! There were tons of AIs there for sale and weren't selling very fast.
