What uses the most energy in a fish tank?
Fish tank electricity use is wildly dependent on a few factors:
- Lighting: Similar to regular light bulbs around your home, different types of light bulbs illuminating your fish tank can of course affect how much power you use and could consequently affect your power bill.
- Heating: The temperature you set and how long you have heating on for may see you charged more for electricity than you expect. You may also see changes in your heating costs depending on whether you are keeping tropical or freshwater fish, as these require different environments.
- Extras: Extra things like water, air pumps, UV filters and plant life alone do not consume much, but together they could add up on your next bill. Consider whether all parts are necessary before implementing them in your tank.
What can I do to reduce the energy usage of my fish tank?
If these figures have left you slightly concerned for the cost of your home fish tank then it might be time to consider some alternatives to avoid higher costs. It may be well worth assessing your heating, lighting and fixtures attached to the fish tank to see if you can opt for more energy efficient models and try to reign in the overall cost. If your keeping a larger tank than you need, it might also be time to consider downsizing, particularly if you have no plans for more fish in the future, to help keep some of those running costs down.
