King British Filter Aid+ 100ml

King British Filter Aid+ enhances your aquarium’s biological filtration by introducing natural denitrifying bacteria that break down toxic ammonia and nitrites. These harmful substances arise from fish waste, uneaten food, and plant debris, posing serious risks to aquatic life. By converting ammonia and nitrites into less harmful nitrates, this product supports a healthier aquatic environment, making maintenance more manageable through routine water changes and plant filtration. Ideal for new setups, after partial water changes, or post-treatment recovery, it is suitable for coldwater, tropical, and marine tanks.
