I have a 6 foot 120 gallon tank that I am looking for lighting for. Its only 2 feet deep so not sure at this point what type of lighting i should get. Im just looking to see what other members might have to sell. Also, Im going to be starting off with a little bit of live rock in the middle of the tank and as I go and get the money, I will be adding more rock to the tank. So at this time Im not sure if I really need a 6 foot fixture or if I could get by with something smaller right now then buy a bigger one latter. I am closing on my house (which is costing $5500 for the down payment) and dont have the money to buy a new 6 foot fixture right now so Im looking at used stuff for the time being. Please let me know what you have. Thanks a bunch.
