Keep your aquarium water crystal clear and healthy for your fish with this 16-pack of PF-L Replacement Filter Cartridges. They're compatible with popular Aqueon/Tetra power filters: PF20, PF30, PF40, and PF75. Each cartridge measures about 6.5 x 4.5 inches (including the handle). They use a four-stage filtration system: a dense dual-sided mesh for mechanical filtration, ultra-activated carbon (specifically nutshell activated carbon, which is great for removing odors and discoloration), and processed spherical zeolite (which helps remove ammonia and balance pH). This combo works to trap debris, absorb pollutants, and create a stable environment for your fish and plants. Easy to install – just rinse under cool water, then slide into the filter chamber. Replace them every 2-4 weeks depending on your tank's bioload. A cost-effective way to maintain a clean, healthy aquarium.
