Selecting the correct external filter is vital for maintaining clear, healthy water and reducing maintenance in your aquarium. The right filter will efficiently remove debris, control toxins, and support beneficial bacteria, helping your fish and plants thrive.

How to Determine the Correct Size

Begin by calculating the volume of your aquarium. Compare this with the specifications provided by filter manufacturers, paying attention to recommended tank sizes and flow rates. As a general rule, it’s better to choose a model with a higher capacity than the bare minimum.

Why Bigger Is Better

You can never have too much filtration, but too little can quickly lead to cloudy water and higher maintenance. Opting for the largest filter within your budget, ideally one that includes a built-in UV steriliser, will enhance water clarity, improve circulation, and reduce the frequency of cleaning both your aquarium and the filter itself.

Final Tip

Investing in a high-quality external filter not only saves time but also helps maintain a stable, healthy environment for your aquatic life.
