FAQ
What type of fish are these filters suitable for?+
These dual outlet mid-range filters are well-suited for smaller, community fish like Neon Tetras, Guppies and Corydoras. They're not ideal for large or heavily bioloading species that require more robust filtration systems.
How often should I clean the filter media?+
Regular cleaning is crucial. We recommend cleaning the mechanical filter media (sponges, etc.) every 2-4 weeks, depending on your tank’s load and how frequently you perform water changes. Rinse thoroughly in old aquarium water – never tap water – to avoid damaging beneficial bacteria.
What size pump flow rate do these provide?+
These filters typically deliver a flow rate of around 300-400 litres per hour, which is sufficient for most smaller aquariums. However, always check the specific product specifications for accurate details as flow rates can vary slightly.
Are these filters quiet to operate?+
Most models are designed for relatively quiet operation, but noise levels can be influenced by factors like pump speed and tank size. Look for models with adjustable speeds for optimal noise reduction if this is a concern.
What kind of filter media do I need to use?+
These filters are compatible with standard aquarium filter media such as sponges, ceramic rings, and activated carbon. Ensure the media you choose is appropriate for your fish’s needs and tank setup; avoid using anything that could release harmful chemicals.
Do these pumps require priming?+
Yes, most of these pumps will require priming before initial use. This involves filling the pump housing with water until the pump cycles on automatically. Refer to the manufacturer's instructions for detailed priming procedures.
Can I connect multiple filters together?+
While possible, it’s generally not recommended to connect multiple filters of this type in series. The flow rate may become too high and could stress your fish or damage the pumps – consult the manufacturer’s specifications before attempting any connections.
What is the warranty on these products?+
Amazon UK offers a standard 30-day returns policy for unused items, and manufacturers often provide a one-year warranty against defects in materials and workmanship. Please check the product details for specific warranty terms provided by the manufacturer.
How do I adjust the pump speed?+
Many models feature adjustable flow rates via a dial or button. Refer to your filter’s instructions manual for specific guidance on how to modify the pump speed and achieve the desired water circulation levels.
Are these filters suitable for planted tanks?+
Yes, these dual outlet mid-range filters are well-suited for planted aquariums. The gentle flow they provide helps distribute nutrients evenly throughout the substrate while also removing waste products – just ensure your plant load isn’t excessively high for this size filter.
