Why is filtration important in an aquarium?

A filter is essential for maintaining clean and healthy water in your aquarium. It removes waste, toxins, and excess food, supports the nitrogen cycle, and helps control ammonia and nitrite levels. Filtration also promotes oxygenation, ensuring your fish have a stable and safe environment.

What are the different types of aquarium filters?

There are several types of filters, but there are three main categories of filters. each suited to different tank setups: - Internal filters – Compact and easy to install, ideal for small tanks but are not able to deal with larger amounts of waste. - External filters - Including hang-on and cannister filters. Hang on filters are popular for small to medium-sized tanks, offering good mechanical and biological filtration. Canister filters are powerful filters providing advanced filtration and are essential for large and heavily stocked aquariums. - Under gravel filters - Uses a plate under the substrate with air pumps or powerheads providing both biological and mechanical filtration. Better for beginner tanks.

What is filter media, and why is it important?

Filter media are materials inside a filter that clean the water by removing waste and harmful substances. The three main types are: - Mechanical media (e.g., sponge, filter pads) – Traps debris and particles. - Biological media (e.g., ceramic rings, bio-balls) – Houses beneficial bacteria that break down waste. - Chemical media (e.g., activated carbon, zeolite) – Removes toxins, odours, and impurities. Using a combination of media ensures optimal water quality and a well-balanced aquarium.

How do I choose the right filter for my tank?

When selecting a filter, consider: -Tank size – Ensure the filter can process at least 4-6 times the tank’s volume per hour. -Fish species – Some fish, like bettas, prefer gentle filtration, while larger fish need strong flow. -Maintenance needs – Choose a filter that is able to process the amount of waste produced in the tank, for example goldfish are known to produce a lot of waste and do best with a caniister filter. A well-chosen filter keeps water clear, removes harmful substances, and supports a thriving aquarium.
