i have had freshwater tanks on and off most of my life, my parents used to raise fish when i was little and i have allways had an interest in fish, i have allways loved the way saltwater tanks look, and am considering buying another tank and trying saltwater, i am probably going to go with 75-100 gallons, what all components do i need, filters,skimers,etc,, is there a fish compatability list anywhere also,
