My 55 freshwater is no longer. It is now a FO/LR tank. Right now I have 50 lbs. of Sand/Crushed Coral and around 35 lbs. of LR. I am using a Magnum 350 with two Bio-Wheel 30's. There are two powerheads as well. The lighting is just the 2 15W lightbulbs that came with the tank. I have 2 triggers a Niger and a Humma Picasso. I will be adding a small lionfish in the next week or two. There/will be photos on my website(link in my signature).
