Description:
The Dynamic Power 400L/H External Canister Filter brings that level of filtration to smaller tanks. Running at 400 litres per hour on just 6 watts, it's one of the most energy-efficient canister filters available, making it a practical choice for a filter that runs continuously, every day of the year.
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.
This model is suited to aquariums up to 90 litres and features four easy-access media baskets that let you build your own filtration stack, whether that's sponge, ceramic rings, activated carbon, or bio media. A flow shut-off tap lets you stop water flow for maintenance without disconnecting hoses, and quick-connect fittings mean setup and post-clean restarts are straightforward with no tools required.
The adjustable flow control lets you dial back the output if needed for sensitive species or heavily planted tanks where strong flow isn't ideal.
A maximum head height of 0.85 metres means this filter is best suited to tanks where the canister sits close to the tank, which is typical for smaller nano and desktop setups. Built from compact PVC casing and SGS approved, it's designed for long-term reliability in both freshwater and saltwater environments.
This filter can be used as a pre filter by connecting it to other canisters in the Dynamic Power range.
Suitable for freshwater and saltwater aquariums up to 90 litres.

How the Dynamic Power 400L/H External Canister Filter Compares
⚙️ Dynamic Power 400L/H External Canister Filter
- 🧺4-Stage Filtration: Uses four filter baskets to provide dedicated space for different stages of mechanical, biological and chemical filtration.
- 🔗Can Be Used as a Pre-Filter: The 400L/H canister can be connected to another Dynamic Power external canister filter to provide an additional stage of filtration before water reaches the main filter.
- 🧽Four Filter Sponges Included: Comes supplied with four filter sponges, providing ready-to-use mechanical filtration media for capturing suspended debris.
- 🌿Keeps Filtration Equipment Outside the Tank: The canister sits externally, keeping the filtration unit out of the main display area.
- 🔧Useful as a Dedicated Mechanical Stage: Can provide an additional filtration stage ahead of your main canister, helping capture larger debris before it reaches the primary filter.
⚪ Basic Internal Pre-Filter
- 🧽Single Filtration Stage: A basic sponge or internal pre-filter generally provides a simpler mechanical filtration stage rather than multiple filter baskets.
- 🔗Separate From the Main Canister: A basic internal pre-filter does not provide the same external canister-to-canister setup available with the Dynamic Power 400L/H.
- 📦Limited Media Options: A simple sponge pre-filter primarily provides mechanical filtration, with less space for building additional filtration stages.
- 🌊Equipment Remains Inside the Aquarium: Internal pre-filters occupy space within the display and remain visible in the aquarium.
- 🔧Less Flexible as an Additional Filter: A basic pre-filter is primarily used to protect or supplement the main filter rather than providing a separate multi-stage canister filtration system.
External canister filtration used to be something you only considered for larger tanks. The 400L/H changes that, bringing proper multi-stage canister filtration to nano and small tanks at an accessible price point. At 6 watts, it costs almost nothing to run, and the four media baskets give you real flexibility over your filtration setup, which is more than most filters in this size range offer.
As a general rule, clean your canister every 1 to 3 months depending on your fish load and how heavily planted your tank is. A good indicator is flow rate, when you notice it dropping, it's time for a clean. Always rinse sponges and biological media in a bucket of old tank water taken during a water change, never under tap water. Chlorine in tap water kills the beneficial bacteria living in your media, which can cause an ammonia spike and harm your fish.
Frequently Asked Questions
What is an external canister filter?
An external canister filter sits outside the aquarium and draws water through an inlet, passes it through multiple stages of filter media inside the sealed canister, and returns filtered water to the aquarium. Keeping the filter outside the tank also helps reduce equipment inside the aquarium and keeps your aquascape cleaner.
How do I choose the right size canister filter?
Choose the model based on your aquarium size, required flow rate, stocking level and available space for the canister. The Dynamic Power range includes models suited to aquariums up to 90 litres, 250 litres, 350 litres and 500 litres. Check the specifications for each variant before selecting your filter.
What type of filter media can I use?
The canister filters can be configured with different types of mechanical, biological and chemical media, including filter sponges, bio balls, ceramic media and activated carbon. The media arrangement can be customised to suit your aquarium and filtration needs.
Can I use filter media bags with the canister?
Yes. Suitable loose filter media such as bio balls, ceramic media or activated carbon can be placed into filter media bags to keep each type contained and make maintenance easier. Make sure the bags and media are positioned so they do not restrict water flow through the canister.
Which models have a UV steriliser?
The 1400L/H and 2000L/H models include a built-in 9W UV steriliser. The 400L/H and 1000L/H models do not include UV sterilisation.
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.
Can the 400L/H canister be used as a pre-filter?
Yes. The 400L/H Dynamic Power canister can be connected to another Dynamic Power canister and used as a pre-filter. This allows it to provide additional mechanical filtration before water reaches the main canister filter.
Can I adjust the water flow?
Yes. The canister filters feature flow control that allows you to reduce the output when needed. This can be useful for aquariums with sensitive livestock, smaller tanks or setups where strong water movement is not desirable.
Canister filters have different maximum head heights. What does that mean?
Maximum head height refers to how high the filter can move water vertically. The available head height varies between models, so consider the distance between the canister and the aquarium when choosing your filter. Keeping the canister below the aquarium and using a suitable hose setup helps the filter operate effectively.
Can these canister filters be used in freshwater and saltwater?
Yes. The Dynamic Power external canister filter range is suitable for both freshwater and saltwater aquarium setups.
