Fully Compatible with URUQ: Aquarium filter cartridge measures 5.7 inches in length and 2 inches in width, making it fully compatible with the URUQ 2gal aquarium starter kits. Ensures a clean water environment, promoting the healthy growth of your fish and aquatic pets

Affordable Long-Term Filtration Maintenance: This pack includes 10 filter cottons and 5 physical filter modules. For optimal performance, we recommend replacing the filter cotton every 1-2 weeks and the physical filter modules every 2-3 weeks

Efficient Permeable Filter Cotton: The thickened white sponge pad uses bionic cashmere fiber technology to filter large impurities and feces, while the fiber cotton absorbs smaller impurities and odors, ensuring clear water. The soft sponge design also allows for excellent water permeability

Superior Filtration Efficiency: Physical filter modules are crafted from non-woven fabric, activated carbon, and zeolite, effectively removes and absorbs 99% of impurities and odors. The physical filter module must be fully wetted before use to ensure proper water flow through and prevent overflow

Effortless Installation: Simply remove the used cartridge, and put new into the filter chamber. Proper filtration is essential for a healthy environment for your fish and aquatic pets. Regular replacements ensure your aquarium stays in top condition
