I realize that any hobby that someone gets into, there is the initial investment for startup and learning curve. The cost of the aquarium and accessories, livestock and stands are something i come to expect when i jumped into this. My main concern with a reef tank is the costs after everything is purchased and running. Metal Halides, PCs, skimmers, pumps and other electric hogs are what im leary about and id just like some feedback from you guys(and girls) about your electric bills and if they spiked at all. The month to month costs is what im trying to pin down and see where i possibly stand in the long run. My main tank would be a 55 gallon reef system or fish only. Any info id appreciate.
