Description:
The largest of the Dynamic Power internal filter range, the Dynamic Power 3-in-1 Internal Filter, 1600L/H combines filtration, water circulation, and aeration in a single submersible unit suited to aquariums up to 400 litres. Running at 1,600 litres per hour on 35 watts, it delivers strong turnover for larger tanks while keeping the simplicity of an internal filter setup.
The three-in-one design handles mechanical and biological filtration through a built-in biochemical sponge, circulates water to prevent dead spots and maintain stable oxygen levels, and aerates through an included air tube that draws air into the water flow.
A maximum head height of 2.5 metres gives it strong lift for an internal filter, making it capable of handling larger tank volumes without losing flow. The unit attaches to the tank wall via suction cups, sits fully submerged, and the replaceable sponge means straightforward media maintenance without replacing the whole unit.
Built from durable ABS for long-term reliability in both freshwater and saltwater environments.
Suitable for freshwater and saltwater aquariums up to 400 litres.

How the 3-in-1 Internal Filter Compares
⚙️ Dynamic Power 3-in-1 Internal Filter
- 3️⃣Three Functions in One: Combines mechanical and biological filtration, water circulation and additional aeration in a single submersible unit.
- 🧽Mechanical & Biological Filtration: The built-in biochemical sponge traps suspended debris while providing surface area for beneficial bacteria to colonise.
- 💨Built-In Aeration: The included air tube draws air into the water flow, providing additional aeration without requiring a separate air pump and air stone.
- 🌊Active Water Circulation: Powered water flow helps circulate the aquarium water and reduce areas of stagnant movement.
- 🔧Replaceable Filter Sponge: The sponge can be removed for cleaning or replacement, allowing you to maintain the filtration media without replacing the entire filter.
⚪ Basic Internal Filter
- 1️⃣Primarily Filtration: A basic internal filter generally focuses on moving water through its filter media, without combining multiple functions into one unit.
- 🧽Filtration Media Only: The included media provides filtration, but the filter may not offer the same combination of mechanical and biological filtration in a single sponge.
- 💨Aeration May Need Separate Equipment: If the filter doesn't include air injection, additional aeration may require a separate air pump and air stone.
- 🌊Filtration Is the Main Function: Water movement is primarily generated to pass water through the filter rather than providing a dedicated three-function setup.
- 🔧Fewer Integrated Features: A basic design may require additional equipment or accessories when you want filtration, circulation and aeration together.
For aquarists who want the simplicity of an internal filter but need the output to handle a larger tank, the 1,600L/H is the natural choice. It covers tanks up to 400 litres without the complexity of an external canister setup, making it a good fit for larger community tanks, grow-out tanks, or setups where simplicity and ease of maintenance matter more than hiding equipment outside the tank.
Rinse sponges in old tank water every 2 to 4 weeks depending on your fish load, never under tap water as chlorine will kill the beneficial bacteria living in the sponge. When sponges eventually need replacing, only replace one sponge at a time for a minimum of 2 weeks before swapping it in. 3 to 4 weeks is safer. This process is known as seeding, the beneficial bacteria from your tank water and existing sponge colonise the new sponge over time. Once colonised, swap the new sponge in and leave the second old sponge in place. Repeat the process when the second sponge needs replacing. This protects your nitrogen cycle and prevents an ammonia spike that could stress or harm your fish. Always disconnect from power before removing the unit from the tank.
Frequently Asked Questions
What does the 3-in-1 internal filter do?
The filter combines mechanical and biological filtration, water circulation and aeration in one submersible unit. Water is drawn through the built-in sponge to trap debris and provide surface area for beneficial bacteria, while the water flow helps circulate the aquarium and the included air tube provides additional aeration.
How do I choose the right size filter?
Choose the model based on your aquarium size, required flow rate and available space. The range includes models suited to aquariums up to 50 litres, 300 litres and 400 litres. Check the specifications for each variant before choosing your filter.
Can this filter replace a separate air pump?
The included air tube provides additional aeration as part of the filter's 3-in-1 design, which can remove the need for a separate air pump in some aquarium setups. Whether additional aeration is required depends on your tank size, stocking level, surface agitation and oxygen requirements.
Can I use this filter in a breeding or quarantine tank?
Yes. Internal filters can be useful in breeding, quarantine and other setups where a simple filtration solution is preferred. Choose a model with an appropriate flow rate for the size and livestock of the aquarium.
Is the filter suitable for freshwater and saltwater?
Yes. The filter is designed for use in both freshwater and saltwater aquarium environments.
Can I adjust the water flow?
The available flow and adjustment options can vary between models. Check the specifications for your selected variant for its flow rate and included controls before choosing it for your aquarium.
How does the sponge provide biological filtration?
The built-in sponge traps particles while also providing surface area for beneficial bacteria to colonise. These bacteria form an important part of the aquarium nitrogen cycle and help process ammonia and nitrite.
Can the filter sponge be replaced?
Yes. The built-in sponge is replaceable, allowing you to refresh the filter media without replacing the entire filter unit.
How do I clean the filter sponge?
Gently rinse the sponge in removed aquarium water when it becomes clogged with debris. Avoid rinsing established biological media under chlorinated tap water, as chlorine can harm the beneficial bacteria living on the sponge.
Does the filter need to be fully submerged?
Yes. This is a submersible internal filter and should be positioned inside the aquarium with the filter operating underwater. Follow the setup instructions for the correct positioning of the air tube and outlet.
