Hello, my Oceanic biocube 29 finally bit the bullet a few days ago. I am now in the market either for a new hood (lights) or a whole new system. I don't have much knowledge in what would be a good tank or not. Evidently the one I currently own is not so great with filtering.I am wanting to go as cheap, but effective as possible. Please leave links, or the specific names of items you have in mind. I am fine to go as small as a 13 gallon tank, but don't want to go bigger than a 30 g. Thanks for your help
