Performance: The primary function of an aquarium filter sponge is to maintain water quality by effectively filtering out debris and providing a habitat for beneficial bacteria. We assessed each product’s filtration efficiency, flow rate, and overall effectiveness in maintaining clean water. High-performance sponges should not only trap particles but also promote biological filtration, which is crucial for sustaining aquatic life.
