The Aqua Care Aquarium Bio Clear Filter is an essential addition to any aquarium, designed to provide optimal water quality and a healthy environment for your fish. Featuring a comprehensive four-layer filtration system, it effectively removes impurities and maintains crystal-clear water. The mechanical filtration utilises a filter sponge and a fine pad within the cartridge to trap debris, while the chemical filtration employs activated carbon to remove odours and unwanted particles. The biological filtration component includes ceramic rings, providing a large surface area for beneficial bacteria to thrive, promoting a balanced ecosystem. This filter is supplied with a venturi to enhance oxygen levels in the water and a spray bar that delivers a gentle, even flow. Plus, it comes with a 1-year warranty for added peace of mind.
