Hi all you marine experts. I am completly a novice when it comes to marine aquaruims. With fresh water fish I am bit of an expert. The marine bug has however bitten me completely. I would like to start my own marine aquaruim but have no idea where to start and what to do. I do have a 200 litre fish tank. Will this be suitable to use as marine aquaruim. Please help me. What is all the equipment that i must buy and where can I buy this??
