It would all depend on what your on the look out for. Like what kind of issues do you think your going to get into? If they have been set up for a good time, the only thing you should have to worry about right now is testing the water. Making sure your Ammonia and Nitrites stay at 0, your Nitrates can runfrom 5-10 with no issues when caring for Anemones.
Hi, I am just getting into saltwater. I am purchasing a tanks from friends...one is around 45 gallons and already set up as a reef tank and it has some annomies (sp) and clown fish..live rock and live sand. It has been setup for a year, but is too big for where it is. The other tank has live sand and water. It is 100 gallons, also comes with all equipment and lights. When I found out you have a 200 gallon salt water tank, I knew you would know all the answers. What things do I need to avoid? I already have a 125 Discus tank and a 55 African Ciclid tank and doing ok. jonelle
