Description:
A high-capacity external canister filter for larger aquariums, the Giantz 2400L/H External Canister Filter delivers 2,400 litres per hour at 55 watts, with an integrated 9W UV steriliser for multi-stage filtration. Suited to aquariums up to 500 litres, it's a capable solution for heavily stocked tanks, large tropical setups, or marine aquariums where maintaining water quality is critical.
External canister filters work by drawing water from the tank through an inlet, passing it through sealed, pressurised media baskets, and then returning filtered water through an outlet. The canister sits outside the tank entirely, keeping your aquascape clean and uncluttered. The UV steriliser targets free-floating algae and waterborne pathogens that mechanical and biological filtration alone can't catch, reducing disease risk and keeping water visibly clearer.
This model features four-stage filtration with easy-access media baskets, an included media kit to get you started without sourcing media separately, quick-connect hose fittings, and a tight cap lock to prevent leaks during operation. A maximum head height of 2.5 metres covers most standard aquarium setups. Built for long-term reliability in both freshwater and saltwater environments.
Suitable for freshwater and saltwater aquariums up to 500 litres.

How the Giantz External Canister Filter Compares
⚙️ Giantz External Canister Filter with UV
- 🧺Multi-Stage Filtration: Uses multiple filter stages and media baskets to separate different stages of mechanical and biological filtration within the canister.
- 📦More Media Capacity: The external canister design provides dedicated space for multiple types of filter media, allowing you to build a filtration setup around your aquarium's needs.
- 🌿Keeps Equipment Outside the Tank: The filter body sits outside the aquarium, leaving more of the display area available for fish, plants and aquascaping.
- 💡Integrated UV Sterilisation: The built-in 9W UV lamp provides an additional treatment stage designed to target free-floating microorganisms and algae in the water.
- 🔧Customisable Media Setup: Accessible media baskets make it easier to choose, arrange and maintain different types of filtration media alongside the additional UV stage.
⚪ Basic External or Internal Filter
- 🧺Filtration Without Integrated UV: A standard filter can provide mechanical and biological filtration, but does not provide the additional UV treatment offered by these Giantz models.
- 💡UV Requires Separate Equipment: Adding UV treatment to a standard filtration system generally means purchasing and installing a separate UV steriliser.
- 📦Less Integrated Equipment: Filtration and UV treatment are handled by separate components rather than being combined within one filter system.
- 🔧More Components to Install: A separate UV unit requires additional connections, equipment and space within your filtration setup.
- 🌿More Equipment Around the Aquarium: Adding separate filtration and UV equipment can mean more components to accommodate around or beneath the aquarium.
Four-stage filtration, UV sterilisation, and a media kit included, all for a tank up to 500 litres. For aquarists who want a complete, ready-to-run external canister setup for a larger tank without having to piece together components separately, this covers everything in one package.
Clean the spiral propeller and casing periodically to prevent heavy debris build-up, which can reduce flow and strain the motor over time. Always disconnect from power before handling. If the pump stops unexpectedly, check for blockages first, the built-in overheat protection will cut the motor if it runs too hot, which is usually a sign something is restricting flow. Clearing the blockage and allowing the motor to cool before restarting is all that's typically needed. Replace the UV globe annually or when you notice a drop in water clarity despite clean mechanical media. UV globes degrade over time and lose effectiveness before they stop working entirely, so annual replacement is good practice regardless of whether the lamp still appears to be on. UV replacement globes are available from most aquarium retailers or online. Check your model's specifications for the correct wattage before purchasing.
Frequently Asked Questions
How do I choose the right Giantz canister filter?
Choose the model based on your aquarium size, required flow rate and the available space for the filter. The range includes a 1,250L/H model suitable for aquariums up to 250 litres, a 1,850L/H model suitable for up to 350 litres, and a 2,400L/H model suitable for up to 500 litres. Actual flow will vary depending on head height, hose length, fittings and other system restrictions.
What is an external canister filter?
An external canister filter sits outside the aquarium and draws water through an inlet, passes it through multiple layers of filter media inside the sealed canister, then returns filtered water to the tank through an outlet. This keeps most of the filtration equipment outside the aquarium and helps keep your aquascape uncluttered.
What is the difference between the three models?
The main differences are flow rate, recommended aquarium size, power consumption, head height and hose connection sizes. The 1,250L/H model is suited to aquariums up to 250 litres, the 1,850L/H model up to 350 litres, and the 2,400L/H model up to 500 litres. The 1,850L/H and 2,400L/H models also include a built-in 9W UV steriliser.
Which models have a UV steriliser?
The 1,850L/H and 2,400L/H models include a built-in 9W UV steriliser. The 1,250L/H model does not include UV.
What does the UV steriliser do?
The UV steriliser exposes passing water to UV light, which can help control free-floating algae and some waterborne microorganisms. It works alongside mechanical and biological filtration rather than replacing either one.
What type of filter media can I use?
The canister filters use multiple stages of filtration and can accommodate different types of mechanical, biological and chemical media. The 1,850L/H and 2,400L/H models include bio balls and ceramic rings to get you started, while additional media can be selected to suit your aquarium setup.
Can I use filter media bags with these canister filters?
Yes. Loose media such as bio balls, ceramic rings or activated carbon can be placed into suitable filter media mesh bags to keep each type contained and make maintenance easier. Make sure the bags are positioned so they do not restrict water flow through the canister.
What does the maximum head height mean?
Maximum head height refers to how high the filter can move water vertically. The 1,250L/H model has a maximum head height of 1.3 metres, the 1,850L/H model has a maximum of 2 metres, and the 2,400L/H model has a maximum of 2.5 metres. Actual flow decreases as the water needs to be lifted higher.
Can I adjust the water flow?
Yes. All three models feature flow control on the inlet and outlet connections, allowing the water flow to be adjusted to suit your aquarium and livestock.
Are these canister filters suitable for freshwater and saltwater?
Yes. All three Giantz external canister filters are suitable for both freshwater and saltwater aquarium systems.
