• Biological foam filtration: The 406 and 407 filter media sponges are designed as corrugated biological foam filters, increasing the surface area by 35% to capture dirt and particles, increase water flow, and serve as a preliminary water quality filter.
• The benefits of activated carbon: The activated carbon in the 406 and 407 filter tanks has a large number of microporous structures that can adsorb odors, pigments, and some organic pollutants in water, making the water clearer. It can also adsorb chlorine gas, heavy metal ions, and other substances in water. When used in conjunction with a filtration system, it can improve water quality safety and provide a more suitable living environment for aquatic organisms
• Ceramic ring function: The ceramic ring inside the 407 filter replacement part is porous and loosely structured, which can filter harmful substances in the water, assist in water purification, and help establish a stable aquarium living environment system. The polished pad can capture floating particles to obtain clear water
