How much will my pond cost to run?

How much electricity will it cost to run my pond pump is a question that we are often asked. And in this current climate, it is a rather legitimate question for any fishkeeper contemplating the idea of starting a new pond project.

In practice, so many factors other than just the pump can impact the way your pond consumes energy at every stage of your project.

For example, choose a spot for your pond which is in full sun and you’ll end up paying more electricity using a higher UV-C than in partial or full shade.

Things like pipework have an impact too, the diameter of your pipe, head and type and the number of bends also impact on your flow rate and pump performance.

And on the topic of a pump, are you using a variable pump? So you can adjust the flow rate according to your specific needs.

For those reasons, in this short blog, we wanted to take a more practical approach and bring value to our readers by giving concrete examples of pond projects where customers have accurately measured their pond energy consumption.

How much will my small pond cost to run?

In our previous blog Pond Filtration Energy Cost published last year, we gave a rundown of the cost of using our EazyPod Complete Filtration system.

Our EazyPod Complete is a mechanical and biological filter system for garden ponds up to 10,000 litres / 2,200 gallons. The EazyPod Complete utilises static K1 Micro, which provides enhanced biological benefits. 

Cost breakdown:

  Filter with UV clarifier built-in: EazyPod Complete = 18 Watts

  Controllable water pump: Varipump 10000 set at 50% = 40 Watts

  Air pump: Airpump 70 Kit = 34 Watts

  Total wattage for the entire filtration system = 92 Watts

  Cost per day: £0.62 / Weekly: £4

How much will my bigger pond cost to run?

Quality Nishikigoi recently did a couple of case-study videos with pond customers using our Nexus 200 series on two pond projects, where Tim’s customers measured electricity consumption using an electric box monitor and give a full breakdown on his YouTube channel. https://www.youtube.com/@TimWaddington
