About This

• Ideal Replacement Filter Pads: Contain 4 sponge pads in total (2 yellow pads and 2 blue pads). Perfectly compatible with Grech/SUNSUN CPF-2500 Pressure Pond Filters.
• Mechanical Filtration: All the sponge filter media pad can effectively trap debris, food residue, wastes or other impurities in water. Prevent them from entering the aquarium to keep water clean.
• Fine Sponge Filtration: With larger contact area with water, the sponge filter pads are helpful for the accumulation of beneficial elements. Provide biological filtration to fully remove excess damaging substances.
• Reliable Material: The sponge pads are made of soft and foldable foam with high elasticity and fine air and water permeability. No worry about sucking up your fish. And they won’t block the normal water flow due to the fluffy inner structure.
• Easy to Use: Before use, rinse it with cool water to remove the outside dust, then fully put it into the filter chamber. Replace it every 2 to 4 weeks to maintain a healthy water environment. (Please unpack and let it stand for 24-48 hours or soak in water before use for best results.)
