Hi, i currently have a 30 gallon tanked that i had freshwater in. I have recently changed tanks to a 75 gallon for my freshwater fish. I am wanting to try to start salt water but ive read over the getting started sticky but im wanting a little bit more direct advice. I am wanting to do ONLY fish if thats possible. I would like to know everything i would need to start and maintain. I dont want any coral or anything unless that is needed. Thanks alot im a bit of a noobie at saltwater i dont really know anything! THANKS!
