Recommended Pump Flow Rates (LPH)
Koi Ponds (High Waste)
0 LPH
1x - 2x per hour
Koi produce significant waste. High turnover removes solids and maintains oxygen. For heavy stocking, aim for 1.5x - 2x.
Goldfish Ponds (Moderate Waste)
0 LPH
0.5x - 1x per hour
Goldfish need regular filtration for clear water, especially without plants present.
No Fish/Plants (Ornamental)
0 LPH
0.5x - 1x per hour
Without organic waste, goal is preventing stagnation and algae growth.
| Pond Type | Turnover Rate | Your Recommendation |
|---|---|---|
| Koi Pond | 1 - 2x per hour | 0 LPH |
| Goldfish Pond | 0.5x - 1x per hour | 0 LPH |
| No Fish/Plants | 0.5 - 1x per hour | 0 LPH |
Pro Tip
It is always better to slightly "over-filter" (1.5x) and have the ability to turn down the flow with a valve than to under-filter and have cloudy, unhealthy water.
Important Considerations
- Filter Capacity: Ensure your pump capacity does not exceed the maximum flow rate allowed by your filter.
- Head Height: The pump's flow rate drops the higher it has to push water.
- Minimum Flow: 0.5x per hour is the absolute minimum to prevent algae.
Quick Reference
- 1 cubic meter = 1,000 litres
- Add 10-15% extra for streams, waterfalls & filters
- For irregular shapes, calculate as oval/rectangle and add 10%
- Measure depth at multiple points and use the average
