I've had my freshwater tanks but I'm deciding now that it's time I take a step and start a salt water aquarium. A friend of mine has a biocube 29 and she said I could just have it. It has a cracked in the back of it somewhere but from how it sounds will be an easy fix. The tank is all stock and been sitting for a year or 2. So where should I start? I domt know much about salt water and the maitinence. Any suggestions help tips anything will help.
