What to Compare Before Buying
- Tank volume: This model is stated for 40 to 75 L tanks. Check your aquarium capacity before choosing an offer.
- Flow rate: The pump is rated at 300 L/h. Compare that against the circulation level you want for the tank.
- Space inside the tank: The unit measures 4 W x 13.5 H cm, so check that it will fit the available space.
- Outlet style: Two outlet types are listed. Choose the version that suits how you want water returned to the aquarium.
- Cleaning routine: The sponge is rinsed in aquarium water and the pump can be separated for cleaning. Factor in whether that maintenance routine suits you.
What Else You May Need
A suitable fish tank is needed, along with space for the internal filter and pump to sit inside the aquarium. If you plan to use the oxygenation function, check that the airline tubing arrangement matches your tank setup.
Before You Decide
Confirm the tank volume, the 300 L/h flow rate and the 4 W x 13.5 H cm size before choosing an offer. Check whether the included outlet style and airline tubing suit the aquarium layout you already have.
