Description:
A step up in output for medium-sized tanks, the Dynamic Power 3-in-1 Internal Filter, 1200L/H combines filtration, water circulation, and aeration in a single submersible unit suited to aquariums up to 300 litres. Running at 1,200 litres per hour on 22 watts, it delivers solid turnover for a medium tank while keeping power consumption low.
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 throughout the tank, and aerates through an included air tube that draws air into the water flow. For tanks in this size range, this can remove the need for a separate air pump alongside your filter, simplifying your setup and reducing the number of devices running in or around the tank.
The unit attaches to the tank wall via suction cups, sits fully submerged, and is straightforward to install and maintain. The replaceable sponge means you're not replacing the whole unit when the media needs refreshing. A maximum head height of 1.6 metres gives it enough lift for most standard internal filter placements. Built from durable ABS for long-term reliability in both freshwater and saltwater environments.
Suitable for freshwater and saltwater aquariums and ponds up to 300 litres.

A practical option for medium tanks where an external canister feels like overkill but you still want solid filtration and circulation. The three-in-one design keeps things simple, and at 22 watts for 1,200L/H the running costs are minimal.
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.
