Have Questions About Pumps?

We have answers. Get quick help for common questions.

What is the purpose of a freshwater aquarium pump?
A freshwater pump helps circulate water throughout your aquarium, ensuring proper oxygenation, filtration efficiency, and even nutrient distribution—especially in planted tanks. It also helps prevent dead spots and supports the overall health of fish and beneficial bacteria.
What types of freshwater pumps are available?
There are several types to choose from. Circulation pumps are used to enhance water flow and prevent dead spots. Powerheads are versatile pumps that can be used with undergravel filters or as standalone flow generators. Utility pumps are often used for water changes, draining, or transferring water between tanks or sumps. Wave makers are ideal for simulating natural flow in aquascapes or river-style biotopes.
Are freshwater pumps safe for fish and shrimp?
Yes, most modern pumps are designed with safety screens or guards to prevent small fish or shrimp from being sucked in. If you’re keeping sensitive species, choose pumps specifically labeled as shrimp-safe or with adjustable flow settings.
How do I maintain a freshwater aquarium pump?
Maintenance typically involves cleaning the impeller, housing, and intake every four to six weeks to prevent clogs and ensure optimal performance. Always follow the manufacturer’s guidelines for disassembly and cleaning.
Can I use a freshwater pump for water changes?
Yes, utility pumps are perfect for speeding up water changes or draining larger tanks. Some models come with hose attachments to make water removal and refills quick and hassle-free.
Do I need a pump if I already have a filter?
Many filters include a built-in pump, but in larger tanks or those with complex layouts, an additional circulation or powerhead pump can improve water flow and reduce stagnant areas. Pumps are also helpful in systems where filtration is external, such as sump setups.
How do I choose the right size pump for my aquarium?
Select a pump that can circulate the tank’s total water volume at least three to five times per hour. For example, a 100-litre tank should have a pump with a minimum flow rate of 300 to 500 litres per hour (LPH). For tanks with high bio-loads or specific flow requirements, consider higher flow rates.
Can I adjust the flow rate of a freshwater pump?
Many pumps come with adjustable flow controls or compatible accessories to regulate flow. This is particularly useful in aquascapes, betta tanks, or low-flow environments where strong currents can stress delicate species.
Are your pumps energy-efficient and quiet?
Yes. At Charterhouse Aquatics, we stock a curated selection of energy-efficient, low-noise pumps from top brands like Eheim, Sicce, Aquael, and Oase—ideal for both home and office aquariums.
