Choose an aquarium filter or pump by the volume of water it has to move. The external canister filters here list flow rates of 1000L/H and 1250L/H for tanks up to 250 litres, and the Giantz submersible pump lists a maximum output of 10000L/H for ponds, water features and marine tanks. There is also a magnetic scraper for cleaning the glass.
How to choose an aquarium filter or pump
An external canister filter. The Dynamic Power 1000L/H and Giantz 1250L/H filters sit outside the tank. The Dynamic Power lists four filtration baskets and mechanical, biological and chemical media, and the Giantz lists a 4-stage stackable filtration basket. Both list a 14W draw and use for freshwater or saltwater tanks up to 250 litres. The Giantz listing says the media is not included.
The 1600L/H submersible filter. It is listed as a 3-in-1 filter, circulation pump and aerator, with a built-in biochemical sponge, suction cups and an air tube. Its listing says it suits tanks up to 400L.
A pump for a pond or water feature. The Giantz 10000L/H submersible pump lists a 155W motor, a maximum displacement height of 5m and a spiral propeller that passes particles up to 7mm. It is listed as suitable for fresh and salt water.
Before you order, match the flow rate to your tank volume as the listing gives it, and check the hose and connector sizes on the canister filters: the Giantz lists a 12mm inlet and a 16mm outlet.

Frequently asked questions
What size filter do I need for my fish tank?

Is there a filter that sits outside the tank?
Yes. The Dynamic Power 1000L/H and the Giantz 1250L/H are external canister filters. The Dynamic Power lists four filtration baskets and the Giantz lists a 4-stage stackable filtration basket. They use hoses to connect to the tank.
Can these be used in salt water?
The canister filters are listed for freshwater and saltwater aquariums, and the Giantz 10000L/H pump says it is suitable for fresh and salt water. Check the product page for the unit you choose.
What can I use to clean the glass?
The magnetic corner moss scraper uses neodymium magnets, and its listing says it lessens the need to immerse your hands in dirty water. It is listed for glass, low-iron glass and acrylic up to 10mm thick.
