FAQ
What type of filter media should I use with these pumps?+
A combination of mechanical (sponges), biological (ceramic rings or bio balls) and chemical (activated carbon) filter media is recommended. Mechanical removes particulate matter, biological converts harmful ammonia into less toxic nitrates, and chemical absorbs toxins.
How often should I clean the filter?+
Cleaning frequency depends on your stocking density. Generally, cleaning every 2-4 weeks is sufficient for smaller tanks with low bioloads. Monitor water parameters closely to determine if more frequent cleaning is needed.
What flow rate do these pumps provide?+
Flow rates vary between models, typically ranging from 300 – 600 litres per hour (LPH). Check the specifications for each individual filter before purchase to ensure it’s suitable for your tank size and fish requirements.
Are these filters suitable for heavily planted tanks?+
These pumps can work well in a heavily planted tank, but consider adding extra bio-media to support increased biological filtration. Monitor nitrate levels regularly to ensure plants are not competing with the filter for nutrients.
What size tubing is compatible with these filters?+
Most of these filters utilise standard 6mm or 8mm diameter tubing, which is readily available from aquarium suppliers. Ensure you purchase the correct length to connect your filter to your tank.
Can I use this pump with a canister filter?+
While technically possible, it’s not recommended. These pumps are designed for submersible use and may struggle to maintain sufficient flow in a larger canister filter system.
What is the warranty on these filters?+
Amazon offers a standard 30-day returns policy for eligible items. Please refer to Amazon's website for full details regarding warranty coverage, which typically extends from the manufacturer.
Do I need any special tools to set up this filter?+
You’ll likely need pliers or a small screwdriver for assembling the filter and connecting tubing. A bucket for water changes is also essential.
How do I maintain the pump impeller?+
Periodically check the impeller for debris buildup. Gently clean it with warm water – never use harsh chemicals or abrasive cleaners that could damage the plastic components.
Are these pumps quiet to operate?+
Most models are relatively quiet, but noise levels can vary depending on flow rate and pump design. Read customer reviews for specific feedback on noise performance before purchasing.
