I have kept and maintined several fresh water takns for years. I recently bought a 20 gal saltwater tank and have had good luck with it for about one year. The other day a friend of mine gave me a 55 gallon all glass tank. I was hoping to make it into a reef tank to include several types of fish and invertebrates. I have a general idea of what equipement I will need but if anyone could give specific products or ideas I would really appreciate it. This project is probly going to take me a year or longer but I need all the help I can get. Thank you in advance.
