Dynamic Power 3-in-1 Internal Filter - 1600L/H

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.
