Please note: in cases of extreme temperature variations due to shallow pond (less than 75cm) or location in continuous direct sunlight (south facing); higher friction losses due to longer hose lengths; or higher delivery heads we recommend discussing your requirements with our technical support team.
All references regarding Oase filter / UVC combinations for special pond sizes are based on Mid-European climatic conditions. For other regions they could differ due to ambient and water temperatures. Need Help? Just email or telephone on 0044 (0) 2392 373735

Rules of thumb
| How to select the correct UVC power for your pond | ||
| Ponds without fish stock: | 1 Watt UVC power per m³ pond volume | |
| Ponds with fish stock: | 2 Watt UVC power per m³ pond volume | |
| Ponds with koi stock: | 4 Watt UVC power per m³ pond volume | |
| Click here to view Oase Ultraviolet Clarifiers (UVC's) page | ||
| How to calculate the required pump flow rate for your pond | |
| Ponds without fish stock: | Turnover capacity (in m³/hr) = pond size/ 8 |
| Ponds with fish stock: | Turnover capacity (in m³/hr) = pond size/ 4 |
| Ponds with koi stock: | Turnover capacity (in m³/hr) = pond size/ 2 |
| Example 1: A 40m³ (40,000 litres) pond without fish would require a 40/8 = 5m³/hr turnover (5000 ltr/hr) | |
| Example 2: A 40m³ (40,000 litres) pond with fish would require a 40/4 = 10m³/hr turnover (10000 ltr/hr) | |
| Example 3: A 40m³ (40,000 litres) pond with koi would require a 40/2 = 20m³/hr turnover (20000 ltr/hr) | |
| Note: A pump should be selected that can achieve the required turnover capacity at the relevant discharge head | |
| The discharge head should include the vertical lift plus friction losses through the pipe work | |
