My name is mike. I an basically brand new to the hobby. I bought a used setup from a guy that had been sitting for a while. Its a 55 gal tank with a t5 lighting system and a coralife protein skimmer. It came with about 60 pounds of live rock and about 25 to 30 pounds of live sand. But like i said it had been sitting for a while and im not even sure if the bacteria is still alive. Anyways im just kinda lost on what to do next. Any advice would be great. I look forward to learning from you guys! Thanks
