The guy I bought the aquarium from had some old reef rock and coral that he also gave me. I took the pieces I was interested in and have had them "cooking" for a few days now. I mixed half new water with half water from my existing tank, took a cup of skum from the skimmer and mixed that all together. Today I took a small piece of "live" rock from my existing tank and added it to my "stew", or "witches brew" as my daughter says. Now we will let this sit and cook for a while before I add it to the tank. I don't know if this is doing anything helpful, but I am not ready to add anything into my new tank yet, so I figured it couldn't hurt. Any thoughts?
