Why we chose it

200 litres an hour matched to a 45-litre tank is a sensible pairing rather than an oversized filter creating a current small fish have to fight. At 5W it's cheap enough to run continuously, which a filter needs to be.

Specifications

Brand: Fluval

Full description

A filter that's too powerful for a small tank creates a current strong enough to exhaust smaller fish, which is why matching flow rate to tank size matters more than just buying the biggest filter available.

Fluval's Mini filter runs at 200 litres per hour and is built for aquariums up to 45 litres, drawing 5W. Fluval describe it as simple, quiet and efficient, suited to smaller coldwater or tropical setups.

Who it's for: owners of a small aquarium, up to 45 litres, who want a straightforward filter rather than an oversized one built for a much bigger tank.
