- Turnover rate: 6 times per hour
- Pump flow rate: 120 gallons x 6 = 720 gallons per hour
This method helps you determine what size return pump you need. It ensures your aquarium has the right water flow and filtration.
Pump Capacity and Dimensions
Choosing the right return pump for your aquarium is key. You need to look at its capacity and size. The capacity, in gallons per hour (GPH) or litres per hour (LPH), shows how much water it can move. This is vital for keeping your aquarium’s water clean and healthy.
It’s important to match the pump’s capacity with your tank’s size. A good rule is to pick a pump that can move the tank’s water 4-6 times an hour. This keeps the water flowing well and spreads out important substances evenly.
| Tank Volume (Gallons) | Recommended Pump Capacity (GPH) |
|---|---|
| 10-20 | 200-400 |
| 30-50 | 400-800 |
| 60-100 | 800-1200 |
| 120-150 | 1200-1800 |
The size of the pump matters too. It should fit in your aquarium cabinet or sump without trouble. Make sure to measure the space and compare it with the pump’s dimensions before buying.
When picking a return pump, like the Sicce return pump, think about its flow rate and size. Make sure it fits your aquarium and moves enough water. This way, you’ll get a smooth and effective water circulation system.
Comparing Centrifugal and Positive Displacement Pumps
