Hi thanks for having me. All ways had fresh water tanks all ways interested in salt so finally decided to convert my 40 gallon flat back hexagon to salt. Just been studying on what I want but my wife and 4 year old done told me what I have to have in it (coral & Nemo). So after I set up this one and get hang of basics I intend on custom building a 670 gallon tank that will incorporate a room that is going to be remodeled in my house. Look forward to any info handed out. Oh I live in south MS by Gulf of Mexico.
