I have just started my marine tank. I have an emperor 400 filter equipped with old media cylinders that are already bacteria filled. I also have another large filter running and a powerhead. My tank is 55 gallons equipped with about 40 pounds of live rock and 20 pounds of live sand. I have 2 damselfish in my tank now and my ammonia levels are beginning to drop substantially. My question is do I need to add a protein skimmer, do I need more rock, and are their any tips anyone could give me since I would value any information to better aid me to support my future wildlife.
