I hope that someone can answer this for me. How much maitanance is there for a salt water aquarium. I think I would like to try my hand at a 30 gallon with anenomes and coral and a couple of fish(not sure what kind). I presently have 2 fresh water tanks and change water once a week along with ferts for the plants. Is it much different with a salty. What kind of filtration and equipment would I need? I do not want to buy a book in case it is too much and I choose not to do it, then I have a useless book. Can someone here break it down for me if possible? Thank you in advance
