Reefing newb
Hello im new to the sw world and am trying to get the correct info on starting my reef tank. I cant seem to get a straight answer . I just picked up a used 40 gal tank. It came with a light setup that has 2 compact flourescent and a little led in the middle, heater and heater controler, one power head, 5 gal of salt mix and about 50lbs of rock that has been out of the water for a few months. I have a couple of questions that i need help with. 1 Is a sump required? I plan to purchase a remora skimmer and and another power head. will this be ok for a reef tank if i also use live rock and sand? 2nd is there anything I can do to reuse the old rock? Can it be brought back to life or should I just purchase all new live rock? I will start with these questions with a promise of more to come. Thanks in advance.
