Choosing a Water Feature
Which water feature suits your pond?
All ponds need water movement. Aside from creating the desired aesthetic effect, water movement is essential for providing oxygen.
Waterfall Selection
Waterfalls give a pleasant visual effect and provide the soothing sound of flowing water. For each 10mm of stream/waterfall width you need 100 litres per hour of water.
| Flow / Height | Flow Required (L/H) |

| Head Height (Height from water level) |
Fountain Selection
Fountain nozzles are a pleasant feature within a pond. Many pond owners prefer this to a waterfall as a means of creating interest and oxygen to the water. Remember fountain sprays can be easily effected by wind, also pumps for fountain nozzles need to have a foam pre filter to avoid clogging. The flow for the typical nozzle in the average pond is 1,000 litres per hour.

Waterfeature Selection
Waterfeatures come in numerous sizes and types. The possibilities are endless; spheres, columns, tiered fountains and water panels. The required flow will vary for every different Waterfeature. Spitters need approx 600 litres per hour and larger feature pieces approx 1,000-2,000 litres per hour.

Calculate Required Flow / Head
Where two or three different features are to be operating in the one pond, the required flow of all features is added together.
