Which pump is suitable for which pond?
The selection of the right pump and the appropriate accessories depends on many factors. Rockworld will work out the optimal solution for your individual needs together with you.
The pond size is not the decisive factor for selecting the right pump. Rather: What should the pump be used for?
- Watercourse, streams, waterfalls
- Filtration
- Fountain attachment, spray nozzles
A pond pump is an essential element of any healthy garden pond. By moving the water within your pond, the pump helps to prevent the water becoming stagnant (which results in the growth of algae). As the pump circulates the water within your pond, oxygen is drawn into the water helping to create a healthy environment for your pond plants and fish. You can also use a pump within your pond to power a water feature – such as a fountain, pond ornament, stream or waterfall.
When choosing a pump we are generally interested in how high we need to push the water up, often referred to as the “head”. The second factor we need to know is what volume of water we need. So when we have these two points we can help decide on a pump. There are several other factor involved in sizing a pump and we have detailed more information here.
So for a typical waterfall we might need to push the water up 1m to the top ledge of the waterfall where the water falls into the pond area. This means it has a head of 1 meter. A typical flow for a waterfall could be 4000 litres per hour for a 300mm wide waterfall.
To support the benificial bacteria that keeps the pond clean and healthy, run the pump continuosly. For best filtration circulate the total volume of pond water every one to two hours.
For example a 1000 litre pond needs a pump strong enough to circulate 1000 litres of water through the filter per hour. The minimum should be 500 litres every hour
