I just got two Rena XP3 Canister Filters and all it came with was some activated carbon and some sponge to filter the water. I wanted to know should I add the Bio-Chem Stars or the Ceramin Rings to allow bacteria to grow. Also should I add Bio-Chem Zorb with the carbon for added filtration. I am setting up a new 180gal fish only tank. It will have 100lbs+ live rock and 100lbs+ reef sand.
