How Much Does It Cost to Run an Aquarium (Heater, Filter, Light) in New Brunswick? (2026)

A typical aquarium (heater, filter, light) (80 W) costs C$0.013 per hour, or about C$4.78 per month at 12 hours a day in New Brunswick. Average running cost

How to lower the cost of running an aquarium (heater, filter, light)

- Cover the tank. An open top loses heat through evaporation.
- Use LED lighting on a timer for 8 hours rather than 12.
