Essential filtration tips: Maintaining a healthy discus aquarium requires understanding and implementing proper filtration techniques. In nature, several cubic meters of water per fish help maintain a clean environment, but this ratio is impossible to achieve in home aquariums. Thus, appropriate filtration based on tank size is crucial to compensate for the reduced natural cleaning capacity.

High Bioload: Discus tanks face high bioload due to frequent feeding and the resulting waste. Traditional filter systems often focus more on mechanical filtration rather than biological, which might not be sufficient for the waste produced by discus fish.

Recommended Filtration Systems:

• Built-in Sump Filters: These are typically integrated into the aquarium stand and provide excellent filtration. They allow for large volumes of water to be processed and are easier to maintain due to their accessibility.
• Hamburg Mattenfilter (HMF): Known for its simplicity and effectiveness, the Hamburg Mattenfilter offers a large surface area for bacterial colonization, crucial for the biological breakdown of pollutants. This type of filter is easy to install and has proven to be highly effective in managing the waste produced by discus fish.

For a discus aquarium, ensuring robust and efficient filtration is vital to emulate the clean, balanced environment needed for the health and well-being of the fish.

Essential Filtration Tips: Functions of an Aquarium Filter

An aquarium filter performs several critical tasks to maintain the health and clarity of the water, essential for both the inhabitants and the aesthetic appeal of the tank.

Biological Filtration:

This is arguably the most crucial function of a filter. Biological filtration involves the breakdown of organic wastes such as food remnants, faeces, and urine by different bacteria. For instance, toxic nitrite is converted into less harmful nitrate. Some specialized slow-moving external filters with low-oxygen zones can even break down nitrate further.

Mechanical Filtration:

This process involves the removal of suspended particles from the aquarium water, ensuring that the tank remains visually appealing. Without effective mechanical filtration, the water would become cloudy and detract from the beauty of the aquarium.

Water Movement:

Proper water circulation is necessary to distribute essential nutrients throughout the tank and cater to the needs of current-loving species like catfish. Additionally, adequate water flow ensures even distribution of heat within the tank, preventing the formation of cold spots that could harm the aquatic life.

Chemical Filtration:

Another vital aspect of filtration, chemical filtration alters the water’s chemical composition. Using activated carbon, dissolved compounds are absorbed and trapped in the filter media, which helps remove odours, discolouration, and various contaminants.

Each type of filtration contributes to creating a stable and healthy environment for fish and plants, mimicking their natural habitats as closely as possible within the confines of an aquarium.

Choosing the Right Filter Media:

Selecting the appropriate filter media is crucial for the effectiveness of your filtration system. Mechanical media, such as sponges and filter floss, capture larger debris and particles. Biological media, like ceramic rings and bio-balls, provide surfaces for beneficial bacteria to colonize. Chemical media, such as activated carbon, help remove toxins and impurities from the water.

Maintaining Your Filtration System:

Regular maintenance of your filtration system ensures its continued efficiency. Rinse mechanical media in aquarium water to remove debris without killing beneficial bacteria. Replace chemical media as needed to maintain water quality. Regularly check and clean all parts of the filtration system to prevent clogs and ensure proper water flow.

By following these essential filtration tips, you can maintain a healthy and vibrant discus aquarium that mimics their natural habitat, ensuring the well-being of your fish.
