Well here it goes. We just got our first salt water tank. 90 gal on stand. Right now I have live sand and live rock in it, also the water that I mixed. A heater, one power head, and a Remora Pro Skimmer. After The water is done with the cycle, I'd like to add some fish and corral. I am confused on the filters. I have a sump box thing that goes in the stand,cabniet. I also have two more pumps. What else do I need as far as filtration?? And how does it all need to be hooked up??
