I had an aquarium several years ago, 20 gallon fresh water but my parents took care of it. I still have this tank, and am wanting to start an aquarium again. I have been taking Biology classes in college and have become more fascinated with marine biology. I would really like to start a saltwater aquarium, as I want reefs and live invertebrates, as well as fish. I have been reading on salt water aquariums, but have not come across anything that is helpful as far as testing and the chemistry of the water. I am also wondering, is it a bad idea to start out with salt water as opposed to fresh? PLEASE help!!?? I just don't even know where to start. What fish to buy? How many? How far to space the introductions out? Nitrates? etc..there is so much I need to learn!
Please, and thank you!
