I currently have a 55g that i am using home depot 2 tube 4' utility fixtures for lighting. I use the 3200 lumen tubes and have two fixtures for a total of (4x40 watt tubes) 160 watts. The tubes were on sale at 2 tubes for $.88, The fixtures were $8.00 so my entire lighting is under $20. If i get around to it I plan to add another fixture in a diy hood.
the tank currently has about 5 fish, half a dozen corals, a ball sponge, a green brittle starfish, an anemone, lotsa plant life, a small refug, and some base rock. All seems acceptable.
I highly recommend you establish a thriving plant growth and then do the rest. In that way the plants get ahead of the algaes, keep the water clean, and establish a balanced eocsystem that takes care of the livestock waste products.
