The primary function of any aquarium filter is to maintain water quality by removing debris, toxins, and harmful substances. We evaluated the performance of each filter based on its flow rate, filtration capacity, and efficiency in biological, mechanical, and chemical filtration processes. Filters that consistently delivered clean water while supporting beneficial bacteria growth were prioritized.
