Electricity and saltwater do not mix well; nevertheless we aquarists need to use a lot of electricity to run our systems, so safety is something that should always be kept uppermost in our minds. Putting power strips and ballast transformers under a tank can be a costly mistake. You only need one leak, a few drops of saltwater, and some of your equipment may be ruined or even worse, cause a fire. Another issue that should be considered is your tanks effect on your power bill. In this case, aquarists need to think about efficiency, because the more efficient something is, the less power it will use. We will want to concentrate on things like pumps that run 247, as well as high power lighting systems that may run many hours a day.
